Who will be allowed to upload the finished game on game platforms? It feels unfair if only the last person can upload the game. It also won’t make much sense if everyone uploads the game
I imagine the "rights" would be split between everyone who worked on it, same as any multi-person project. At the very least everyone who worked on it should get mentioned wherever the thing ends up.
I also think worrying about "rights" before the project even makes it to day 2 is a bit presumptuous.
