Who hasn’t spent sleepless nights pondering what would happen if we applied Vilfredo Pareto's (the early 20th-century Italian economist) theories to Mario, the Mushroom Kingdom’s Italian high-jump champion and part-time elephant cosplayer? Data scientist Antoine Mayerowitz, PhD, tackled that age-old question, and the resulting work provides an objective way to tell us the best Mario Kart 8 racer combinations. Hint: It sure as hell ain’t Koopa Troopa.

When you break down the build options (including driver stats and various vehicle details) in Mario Kart 8 Deluxe, there are over 700,000 possible combinations. Yikes. But once you eliminate duplicates that differ only in appearance, you can narrow it down to “only” 25,704 possibilities. How do you narrow it down to find the best racer from there? Enter Mr. Pareto.

Pareto’s theories, most notably the Pareto front, help us navigate the complexities of choice. They can pinpoint the solutions with the most balanced strengths and the fewest trade-offs. Pareto’s work is about efficiency and effectiveness. Now we’re talking.

Nintendo

When choosing a Mario Kart racer, you have to consider their stats for speed, acceleration, handling, weight, offroad and mini turbo. That’s a lot to weigh.

Even if you decide that speed and acceleration are the most important, you’re still left with imbalances. For example, it’s tempting to go all in on speed (like Bowser or Wario), but they have weak acceleration. However, if you prioritize acceleration instead (such as Baby Mario or Dry Bones), you may be left with quick surges that plateau at a lousy top speed.

Meanwhile, some racers are always dominated in the most important stats — meaning their balance of speed and acceleration consistently comes out behind. Koopa is one example of that, so don’t pick him if you care about winning. (But you can absolutely choose him because he has cute bug eyes and a snazzy shell.)

Nintendo

Mayerowitz’s Pareto front analysis lets you narrow your possibilities down to the 14 most efficient. And it turns out the game’s top players were onto something: One of the combinations with the most ideal balance of speed, acceleration and mini-turbo is Cat Peach driving the Teddy Buggy, roller tires and cloud glider — one already favored among Mario Kart 8 competitors.

Of course, if that combination isn’t your cup of tea, there are others that allow you to stay within the Pareto front’s optimal range. As Eurogamer points out, Donkey Kong, Wario (my old standby, mostly because he makes me laugh) and Princess Peach are often highlighted as drivers, and you can use Mayerowitz’s data fields to find the best matching vehicles. Keep in mind that others have identical stats, so racers like Villager (female), Inkling Girl and Diddy Kong are separated only by appearances.

To find your ideal racer, you can head over to Mayerowitz’s website. There, you can enter your most prized stats and view the combos that give you the best balance (those highlighted in yellow), according to Pareto’s theories.

Rebel Moon: Part 2 - The Scargiver is an empty feast. It's a relentless onslaught of explosions, sci-fi tropes and meaningless exposition that amounts to nothing. And yet somehow it's still better than the first film in Zack Snyder's wannabe sci-fi epic franchise for Netflix, Rebel Moon: Part 1 - A Child of Fire. (What do these titles really mean? Who cares.) 

With all of the dull table-setting complete, Snyder is able to let his true talents soar in Rebel Moon: Part 2 by delivering endless battles filled with slow-motion action and heroic poses. It looks cool, I just wish it added up to something. Anything.

Spoilers ahead for Rebel Moon: Part 2.

If you somehow missed the first Rebel Moon film, the basic setup is that it's Star Wars meets The Seven Samurai. Sofia Boutella stars as Kora, a former elite soldier of an evil empire who is hiding out in an all-too idyllic farming village, just planting and harvesting her days away. When a group of military baddies kills the chief of the village and starts threatening a young girl, Kora goes on a murdering spree (in defense!), leaving the community open to a retaliatory attack. 

She spends the first movie recruiting potential warriors to defend the village, including a fallen gladiator (Djimoun Hounsou) and a bad-ass swordswoman (Doona Bae). (Their names are Titus and Nemesis, respectively, but those don't really matter because the characters are paper thin.)

Full disclosure: I tried writing a review for the first Rebel Moon and just gave up in disgust. It was a shockingly boring epic, so much so that it took me several days to watch without falling asleep. By the end, I was only left with a feeling of dread, knowing that there was still another two hours of Rebel Moon ahead of me.

It's somewhat empty praise, but at least I didn't fall asleep during The Scargiver. Mostly, that's due to the film actually having a sense of momentum and a lot more action. You can turn off your brain and enjoy the pretty pictures, much like you could for Snyder's Sucker Punch, Justice League and Watchmen adaptation. He's more a stylist than a natural storyteller, but occasionally Snyder's visuals, such as a baffling montage of our heroes harvesting wheat, can be almost poetic.

Netflix

It's just a shame that I didn't care much about the film's characters or any aspect of its story. James Gunn's Guardian's of the Galaxy trilogy made us fall in love with a band of misfits and screwups, with storylines that directly led to their personal and emotional growth. The crew in Rebel Moon, instead, feel like cardboard cutouts from better movies, and the overall plot feels forced (there's even setup for another film by the end). 

Hounsou tries to sell the pathos of Titus with his eyes, but he can only do so much. And while Bae's warrior woman exudes cool (and has a very compelling flashback), she's mostly wasted when the action really heats up. Then there's Jimmy, a robot voiced by Anthony Hopkins, who is briefly introduced in the first film and pops up for a few minutes here to kick butt. Why? It doesn't matter. Somehow that character is also important enough to serve as the narrator for both Rebel Moon films (but really it seems Snyder just wanted Hopkins' voice adding gravitas).

Perhaps the only real saving grace for Rebel Moon: Part 2, much like the first film, is Ed Skrein as the villainous Atticus Noble. As a sadistic baddie, he's really nothing new, but Skrein's heightened scenery chomping makes the character interesting to watch. Where Darth Vader exudes a calm sense of dread, Skrein's Noble is entertainingly chaotic, like the Joker crossed with Christoph Waltz's Hans Landa from Inglorious Basterds. He just has a lot of fun being bad — that's something!

Given how popular the first film was (according to Snyder and Netflix, anyway), we'll likely see more Rebel Moon down the line. Snyder previously said he'd like to do a six-hour director's cut of both films, and he recently told Radio Times that he'd like to stretch the Rebel Moon series out to four or six films. Somehow, that just feels like a threat.

It hasn't been a great week for Paradox Interactive, and things just got a little worse for the publisher. It has announced another delay for Prison Architect 2, the sequel to a cult hit from 2015. The game had been set to drop on May 7 (which was already a delay from March 26) but now it won't arrive until September 3.

Though builds of Prison Architect 2 had been certified for all platforms, the developers at Double Eleven ran into some technical problems that will take some time to resolve. Some issues concerning memory usage and minimum spec configuration failures emerged. Although the team says its work on fixing those have been successful so far, some other technical challenges started popping up, leading to significantly more crashes.

Double Eleven will use the extra development time to improve the prison management sim's stability and to refine some of its features. Paradox says it will also take the opportunity to let players get a look inside the development process via additional developer diaries and streams. A stream is set for April 25.

Paradox notes that console players who pre-ordered will automatically be refunded due to platform policies — they'll need to buy Prison Architect 2 again to get a pre-order bonus. Steam players can request a refund if they wish.

The Prison Architect 2 delay comes one day after studio Colossal Order said it would refund all players who bought the first asset pack for Cities Skylines 2, another game Paradox is publishing. While the asset pack (which will be added to the base game for everyone) worked, there appeared to be a consensus among fans that there wasn't enough in there to justify the $10 price. There are bigger issues at play though, as Colossal Order has more work ahead to optimize Cities Skylines 2 after a rocky debut. The studio has also delayed the console release and other DLC as it focuses on fixing the core concerns.

Do you like rip-roaring science fiction books? Do you like movies? Then you are in for a treat in, well, two years. Amazon MGM Studios just set a release date of March 20, 2026 for Project Hail Mary, according to Deadline. It’s based on the Andy Weir novel of the same name, which was one of our favorite books of the past few years, so color us excited.

The film stars honorary SNL cast member Ryan Gosling and will be directed by Phil Lord and Christopher Miller, the duo behind The Lego Movie and, allegedly, most of the good parts of Solo: A Star Wars Story. Lord also wrote a little-known movie called Spider-Man: Into the Spider-Verse.

The script was penned by Drew Goddard, who cut his teeth on TV shows like Buffy the Vampire Slayer and Lost before moving onto features. He directed Cabin in the Woods, which is somehow both iconic and underrated at the same time. If the name Andy Weir sounds familiar, it’s because he wrote a book called The Martian, which inspired the Matt Damon film. Incidentally, Goddard also wrote that script.

I’ve read the book and loved it. It’s more fantastical than The Martian, but still filled with the same science-based solutions to massive life-or-death problems. This time, the entire Earth is on the chopping block, instead of one lone astronaut. It’s also pretty dang funny, just like The Martian, so Lord and Miller are a good match to direct. The pair also signed on to direct an adaptation of another Weir novel, Artemis, but that project looks to have stalled.

Or course, a lot can happen in two years. Here’s to hoping our humble little society keeps clunking along so we can chomp down some popcorn in 2026. Speaking of, that year will also see the release of The Mandalorian & Grogu, the Rey Skywalker film, the sequel to The Super Mario Bros. Movie, Toy Story 5, The Batman Part II and, reportedly, Avengers: The Kang Dynasty.

If you’re looking to automate more of your home cleaning setup, iRobot’s flagship Roomba Combo J9+ is on sale for $400 off. The vacuum-mop hybrid robot, which only arrived last fall, has a redesigned dock that automatically empties debris and refills the device’s mopping liquid. Usually $1,399, Wellbots has the Roomba Combo J9+ for $999 with coupon code ENGA400.

The Combo J9+, Engadget’s pick for the best vacuuming-mopping robot, has an upgraded motor and four-stage cleaning system that takes multiple pass-throughs across your carpets and floors. This version also adds dual rubber brushes for better suction and pressurized scrubbing. Its motor automatically lifts the mop pads when it reaches carpets and rugs to help keep them dry.

The robot requires minimal setup, and its new Clean Base can automatically refill the water tank, leaving you with fewer things to worry about. The base doubles as a storage unit and appearing less like a gadget’s charging station and more like living room furniture. Setup is as simple as adding water and cleaning solution to a reservoir and attaching a mop pad. Upkeep is limited to swapping mop pads and leaning the vacuum’s bristles and dust bin.

The Combo J9+ ships with Roomba’s OS 7, a new software update that streamlines more of the cleaning process. Its Dirt Detective feature remembers your home’s dirtiest areas and tackles those first on subsequent cleanings.

The software has an automated setting that saves bathrooms for last, so you don’t have to worry about tracking grime and bacteria to other parts of your home. (You can manually override that if you want it to get to the bathroom earlier.) Speaking of bathrooms, the machine includes iRobot’s Pet Owner Official Promise (P.O.O.P.), which guarantees a replacement unit if your device accidentally sweeps up pet waste.

iRobot

For those who don’t mop much, Wellbots also has the standard Roomba J9+ for $300 off ($599) when you use code ENGA300. It includes all the vacuum-related features from the more expensive Combo variant, including a three-stage cleaning system, multi-surface rubber brushes and stronger suction.

Finally, the previous-generation Roomba Combo j7+ offers an older (but still high-end) vacuum-mop cleaning robot for $200 off with coupon code ENGA200. Although you lose some of the features of the newer model, it still has a 96.4 percent debris removal rate, obstacle avoidance, and a four-stage cleaning system. Its cleaning toolbox includes an edge-sweeping brush, dual multi-surface rubber brushes, power-lifting suction and the mop. The device can even return to its base when it’s full and continue emptying itself for up to 60 days, leaving you to focus on things that aren’t cleaning.

Tesla has issued a recall for around 3,878 Cybertruck vehicles, a National Highway Traffic Safety Administration notice has revealed. Apparently, the cover of the truck's accelerator pedal could get dislodged and trapped by the interior rim. Based on videos going around showing the problem, a faulty accelerator cover could slide up due to excessive lubricant, jamming one end into a crevice while it's still also attached to the pedal itself. That means the vehicle could get stuck accelerating in full power even after the driver lifts their foot. 

Tesla said in the notice that it will replace and repair the pedals as needed free of charge. The automaker will send notices to owners of recalled Cybertrucks in June, but affected drivers who want their vehicles to be fixed as soon as possible can also call the company's customer service number at +1-877-798-3752. If asked for reference, they can say that the recall service number for their issue is SB-24-33-003.

Cybertruck buyers were recently informed that their deliveries had been delayed and were reportedly told that Tesla was going to issue a recall over a problem with the vehicle's accelerator. It followed an earnings call earlier this month, wherein the company revealed that it experienced its first year-over-year drop in deliveries since 2020. Tesla didn't share how many Cybertrucks it shipped exactly, but its shipments were down 20 percent compared to the fourth quarter of 2023 and eight percent compared to the same period a year ago. A couple of weeks later, reports came out that the company is laying off more than 10 percent of its workforce to reduce costs and increase productivity. While all that information only came out over the past month, Tesla has been expecting a leaner year from the start, with Elon Musk previously warning shareholders that they will likely see "notably lower" sales growth for 2024.

The latest batch of rumors make it pretty clear that a PlayStation 5 Pro is coming this year, but will anyone really care about slightly better 4K graphics? This week, Engadget Senior Editor Jessica Conditt joins Cherlynn and Devindra to chat about the PS5 Pro, as well as her piece on the PlayDate two years after its release. You could say the Playdate is pretty much the opposite of another expensive high-end console. 

In other news, we discuss the death of Boston Dynamic's hydraulic Atlas robot, and the birth of an all-new digital model. We also chat about the abrupt closure of Possibility Space, an ambitious indie game studio.

The bill that could ban TikTok in the United States inches closer to becoming law. The legislation passed the House of Representatives last month, then had to face the Senate — and opposition from a few prominent lawmakers. The House is to vote on a package of bills this weekend, which includes a slightly revised version of the TikTok bill. In the latest version, ByteDance would have up to 12 months to divest TikTok, instead of the six months initially pitched.

That change alone was apparently key to winning support from some skeptical members of the Senate, including Sen. Maria Cantwell, chair of the Senate Commerce Committee. What will happen if the bill passes into law? TikTok (and potentially other apps “controlled by a foreign adversary”) would face a ban in US app stores if it declined to sell to a new owner.

Apple says it was ordered to remove WhatsApp and Threads from China App Store

Chinese regulators cited national security concerns.

… and in what you might believe is something of a tit-for-tat move for blocking TikTok, Apple has pulled WhatsApp and Threads from the Chinese App Store. The country’s internet regulator says the removal was required and justified on national security grounds. Apple is always willing to comply, lest it harm relations with one of its largest markets.

Analogue Duo review

A second chance for an underappreciated console.

Tim Stevens for Engadget

Analogue’s latest retro console takes us to the multimedia era with the Duo: a love letter to one of Japan’s most beloved (but niche) consoles, the TurboGrafx-16. It’s a deep cut from a brand that has made its name reviving the most obscure hardware from gaming history. But, as much as you can emulate all of these titles on pretty much any device you have laying around, there’s something different about running it from the original media.

Netflix is done telling us how many people use Netflix

There’s no penalty for secrecy if you’re a streaming company.

Netflix has always been secretive about how much of its near-limitless library of content is being watched at any given time. Now, the company has said it will even stop disclosing how many subscribers it has to prevent giving Wall Street another stick with which to beat it. Instead, it’ll only drop data when it’s good PR, like crossing the 300-million subscriber threshold, and stick telling everyone how much money it’s making.

Amazon's live adaptation of Fallout was so well-received, the fourth main game in the franchise had a resurgence in sales almost a decade after it was released. If you were ever worried about its fate despite the success it enjoyed, you can rest easy, for now: Amazon has already renewed the show for a second season, mere days after the first one debuted. The Fallout universe is set in a post-apocalyptic world, decades after a nuclear war decimated the planet. Ella Purnell plays Lucy in the series, a vault dweller who was forced to go to the surface to rescue her father.

Walton Goggins seems to be a hit with audiences as the Ghoul, a radioactive noseless bounty-hunting corpse. We called him an "enlightened choice" for the role in our review and found this to be his most engaging performance yet. As a whole, we liked Fallout almost as much as we liked the TV adaptation of the The Last of Us. It features fantastic visuals with detailed sets and costumes that stay true to the source materials, and it has a story that flows well and doesn't feel like it's struggling to juggle several different plotlines. The game is also violent and gory, though, and it's not really for the faint of heart. 

The show is one of Amazon's projects under executive producers Jonathan Nolan and Lisa Joy, the creators of Westworld, who Prime Video signed back in 2019. "We can’t wait to blow up the world all over again," Nolan and Joy said, indicating that they'll be back for the next season, though Amazon has yet to announce when it will begin production or if it has a timeline for the project.
