You named your game after a well known psychological experiment and now you’re surprised someone else used the name and generalized gameplay related to said experiment? Not trying to be that guy but brother, what were you expecting? Did you have another in the tank called The Stanford Prison Experiment? The Rorschach Test maybe? Kinda comes with the territory I would think.

But for real, just call it Milgram. Conveys the same thing, no crossover with duplicate, I think it would show up first in a search on steam as well.

It’s been adjudicated before: you can’t. It’s the reason PUBG and Fortnite can coexist even though Epic completely ripped off PUBG after helping develop the game. It’s also why the “DOOM clone” genre was allowed to proliferate into the FPS genre, why there are so many FNAF-inspired games, and why Nintendo recently lost one of its Pokémon patents. You don’t own the concept of the Milgram experiment, you don’t own the trademark for the name, and the overall gameplay concept is not subject to copyright. Unless you can prove that the other developer stole code or art assets from you, or that it violated a trademark or patent that you own, there’s nothing you can do but hope that the better product wins in the end.

They may have done you a favour. The name just being the name of a famous experiment is not very SEO friendly. The less of your troubles is another game having the same name, you have thousands of references to that experiment to compete with for name placement.

You’ll need to add onto your tile, to distinguish it from the rip-off version, so people know.

And, doing what you’re doing here, getting the word out.

You’ll be fine.

Unless you trademark the title you can’t do anything about it. And an international trademark cost a lot of money.

I wouldn’t worry too much about it. The copy doesn’t look like a game that can compete. It looks very barebones. The Steam algorithm will bury this game because it won’t sell. You probably gave this game more publicity than it ever got before. Just focus on your own game the more wishlists you get the more the algorithm will push your game to customers and they will never see the copy.

I wish listed your game, I’ve been following it for some time, looks a lot better than the copy. I don’t think that copy will sell as much, and if you keep promoting and talking about it the way you already are, I think it’d be clear which one is the rip off.

I think it’d be a good idea to give keys to some streamers to show the game. I might tell a few steamers to stream this, it seems like it would be fun to do this with an audience.

Yours looks way better, one small criticism that may be easy to adjust but could also just be the visual style you want: most surfaces look way too glossy and reflective.

While it’s nice to have detailed reflections, things like the wall tiles just seem nearly like mirrors when it comes to light reflections. There’s no diffusion. Maybe the face masks could stay as glossy, but I would diffuse/dull the rest a bit. The ceramic tile but especially the padded room. Padded room tiles would be fabric so there really shouldn’t be any gloss and very little reflection.

I hope you don’t take that the wrong way, and I think your game will stand out as far superior to the copy

Make it easy on yourself

Find a new name for your game

Happened to bigger outfits. There is this board game “Settlers of Catan”, which should have been “Settlers” originally, until a computer game of that name got released just before they launched.

I added yours to my wishlist, though I don’t intend to play it cause horror doesn’t sit well with me on account of how I’m a giant wuss but I still support artists, and I put theirs on my ignore list.

I wish listed yours so hopefully that helps the algorithm a tiny little bit

All I know is yours actually looks good. Theirs feels like one of those minis where it has 1/10th the heart and the whole fascist democracy ‘be a good citizen’ thing in theirs is trying to tap into something helldivers made popular for a surge and didn’t even do well. I’ll be getting your game when it drops if I can, but theirs isn’t interesting.

You could maybe make a trademark complaint against them if you have been using the name of your game publically before they have, which from your steam page already existing I would assume you’ve been using it publicly for at least a little while now. As to how you would go about making such a complaint, I don’t know what to do other than talking with a lawyer if Steam doesn’t have any sort of option. This all assumes you live in the USA, if you’re in another country different options may or may not exist.

Let me just say your game looks awesome and I look forward to its release.

I think you should report it to steam, you’ve surely had a page with that name for longer. I wouldn’t change your game name now

I’m surprised that it’s allowed to have 2 games with the same name on steam (I guess their Steam IDs aee different). I wonder how steam handles their directories in the /steams/common folder if they have the same root folder name.
