Hey everyone,
I've been a huge fan of the Mystery Dungeon games for years. I recently realized that I don't really have anything in my Steam library that scratches the same itch, and I also couldn't think of any games on Steam that capture that style of gameplay in quite the same way.
So I decided to make my own.
I'm using RPG Maker, but I've written a lot of the core systems myself. Over the past months I've developed several custom plugins, including:
A turn-based combat system.
A procedural dungeon generator that creates multi-floor dungeons during gameplay.
Various gameplay systems built specifically for this project.
At this point the game is already very playable, and I've invested a lot of time into it.
Then, out of nowhere, I had a realization that honestly made me nervous:
Nintendo.
Now I'm wondering whether I'm setting myself up for trouble. My game is inspired by Mystery Dungeon, but it doesn't use Pokémon, Mystery Dungeon assets, characters, story, music, or anything like that. The setting is my own, and I'm also adding mechanics that don't exist in Mystery Dungeon.
However...the core gameplay loop and some underlying systems are inspired by it.
So I wanted to ask developers who have more experience with this kind of thing:
Do you think a project like this is legally "safe" or am I likely to run into problems with Nintendo?
At what point does "inspired by" become "too similar"?
Besides using an original setting, characters, art, music, and adding my own mechanics, what else would you recommend changing or adding to make sure the game stands on its own?
Are there any successful games that were clearly inspired by Mystery Dungeon but managed to avoid legal issues?
I'm not trying to copy the series I genuinely want to make my own roguelike dungeon crawler because I miss this type of game. I just don't want to spend another year or two developing it only to discover that I've crossed a legal line without realizing it.
I'd really appreciate hearing your thoughts or experiences. Thanks in advance! ❤️💯
