This is an amazing subforum and a wonderful threat. Let me just give a little more of life to it.
Yes, more of it is really rough, but Im just creating code overall for these fan games. I also never studied "officially" any language, I just learned through the years in my spare time. What I mean with this I mean anyone can do a game. (I even finished and published one mobile game, but I think it is also lost media lol, im not paying 75 bucks)
Recently I finished a build of a fan made third person fan-game based on the Girls Frontline universe:
What im currently working on is a mario party like fan-game with characters of Hololive. This one is specially rough, but Im still working on it. I aim to just finish a simple build with 3-4 really simple minigames and with like 5 turns.
Im also trying to build a simple doom-like fps on the dreamcast with Raylib, but this is really on the basic stuff, my hands have been full atm.
So yeah, if I could make this anyone can. I recommend Unity rather than other alternatives: there is a lot of documentation and help, and C# is a well known and simple language as well.
