I'm still relatively new here, but I am willing to at least try to pick up the numbers, both because I think it is interesting, and because it compliments RolStoppable's first party thread quite well. But with no idea where the previous two thread owners were at, perhaps it might be better to just start over from scratch?
Probably something a bit simpler. User, games list, physical or digital, attach rate. Maybe not a separate members list, since that really just doubles the work for little value, imo.
