There should definitely be a breakdown of groups by genre, and maybe even by how far along the game is in development. Maybe each month have a little "sign up" for those groups and at the end of the month have a discord meeting or something so people can upload what it is they got done. Or maybe even treat it similar to a game jam where people can upload little demos of their progress for feedback? I dunno, just spit-balling based on what I used to do in writing groups.
We would just kind of give everyone a "turn in" date for the group that signs up. Read and review everyone's work over the week, and at the next meeting talk about it. Not sure if that could translate as easily in game dev.
