TLDR / PSA: The Nintendo eShop is selling what appears to be mass-produced, AI-generated shovelware with misleading descriptions that make these apps sound like actual games. I only discovered this AFTER buying Judo Master Rising, which turned out not to be a game at all. Just a warning to others: be careful what you’re buying, because apparently Nintendo allows this crap on its store.
My kid does judo, so when I stumbled across Judo Master Rising on the Nintendo eShop, I thought I’d found something he’d really enjoy.
I imagined an actual video game where you control judoka with the Switch controllers, learning different grips and throws step by step. Pressing buttons to perform the movements, gradually learning more complicated techniques, maybe even working your way through the ranks.
Basically, a game that teaches you judo through gameplay.
And honestly, that’s pretty much what the eShop description made me expect.
Here’s the literal description from the Nintendo eShop:
Master the art of throws, holds, and self-control through an immersive journey into judo.
Designed for all levels, each step builds your strength, focus, and technique.
Practice with realistic drills and intuitive lessons that grow with you.
Develop the mindset, movement, and discipline of a true martial artist.
Train with purpose and rise through the ranks.
(Software description provided by the publisher.)
Sounds like some kind of interactive judo game, right?
I wasn’t expecting some incredibly sophisticated martial arts simulator for a few euros. Just a fun game where my kid could actually perform judo techniques with the controller and learn something about the sport he loves.
Well, what a waste of money.
IT’S NOT EVEN A GAME. LITERALLY.
What I got was basically a really shitty PowerPoint presentation. Page after page of lengthy text, with a static illustration underneath each one. No animations, no characters performing throws, no interactive exercises, no gameplay whatsoever.
You can’t even navigate it with the regular Switch controllers. It’s touchscreen only.
And I’m 100% convinced this thing was churned out using AI.
The illustrations are absolute nonsense.
One shows two judoka somehow grabbing each other’s hands in a way that doesn’t even make anatomical sense. One of the hands seems to have disappeared entirely. And instead of demonstrating a proper grip on the sleeve and lapel, they’re doing… whatever the hell that is.
Another illustration shows two judoka with their arms stretched out like they’re figure skating. There’s no proper grip, no visible control over the opponent’s balance, and absolutely nothing useful to learn from it.
These aren’t just ugly pictures. THEY’RE SUPPOSED TO BE TEACHING JUDO.
I didn’t buy this to read a judo manual or have my kid physically practise throws in the living room. I bought it because I expected an actual video game where she’d get to perform judo techniques virtually, using the controller.
Instead, I got walls of text and AI-looking illustrations that don’t even demonstrate the basics correctly.
And then there’s the part that really pissed me off.
AFTER purchasing the software, there’s a little information button that reveals this disclaimer:
This is an informational app related to the downloaded topic. It is not a game and does not include any gameplay features, other than serving as a practical guide.
I’m sorry, WHAT?!
So the publisher explicitly acknowledges that it’s NOT a game and contains NO gameplay features, but somehow that information didn’t make it into the eShop description?
Instead, they advertise realistic drills, intuitive lessons, an immersive journey into judo and progressing through the ranks.
What exactly am I supposed to be practising here? My reading comprehension?
Then I looked up Lunaria Games, the developer and publisher.
And suddenly things started making a lot more sense.
Apparently, they’ve published dozens of cheap educational and lifestyle titles on the Nintendo Switch, covering everything from martial arts and yoga to skincare, dog training, financial advice and relationship skills.
They even released four different titles on the exact same day as Judo Master Rising.
Now, I find it pretty hard to believe that a developer pumping out this many apps on completely unrelated subjects is carefully researching, writing and illustrating every single one.
Especially after seeing the garbage they sold me.
I’m convinced Judo Master Rising was largely generated using AI, and I strongly suspect they’re using the same approach, probably with reusable templates, for a significant portion of their other educational apps.
So I did some digging. Here are the other Lunaria Games titles I found that I’d be VERY cautious about:

Obviously, I haven’t bought or tested all these other titles, so I can’t tell you whether they’re equally terrible or actually AI-generated. But given the sheer number of unrelated subjects, how quickly they’re released, and what I’ve personally seen in Judo Master Rising, I have some serious doubts about the quality of these apps.
And before anyone says “what did you expect for a few euros?”, that’s completely missing the point.
I don’t care whether something costs €5 or €50. If you’re selling an informational app with zero gameplay, THEN SAY SO ON THE STORE PAGE.
Don’t advertise realistic drills, intuitive lessons and an immersive training experience, only to reveal AFTER purchase that there’s literally nothing to play.
Especially when Nintendo generally doesn’t offer refunds for digital purchases.
I’ve attached screenshots of the actual eShop description, the disclaimer inside the software and some of the ridiculous illustrations.
If you’re considering buying Judo Master Rising, save your money. And I’d seriously think twice before buying anything educational from Lunaria Games.
Nintendo, how is this crap allowed on your store?
