Any interest in a Lemmy users gaming group?

What would be a good game(s) for Lemmy users to start a group and play? I get people like different things, but it should be FOSS or free and accessible to anyone on Lemmy.

In short, something fun, MULTIPLAYER , and approachable for all ages. Not AAA or fees, and needs to be casual.

Possible to form a Lemmy group and pick a few games to rotate.

Respond with creative ideas and suggestions.

If for some reason you think this is a terrible idea please express it with an explanation, so it can be remedied rather than dismissed.
