The actual title of today’s prompt is “What game is your group most likely to play next?” That question makes a few assumptions, the foremost being that one plays in a single group.
Take a look at Rich Rogers. Inferring from his posts about gaming and invitations to game (or watch one being streamed), I don’t think he actually has a game group, just a whole bunch of gamer friends that come together to play stuff for a few sessions and then back to the pool. Or if he does have a game group, he has at least three, each with a revolving cast, maybe some regulars in each. (Rich, don’t tell me. I want to believe you live in a magical wonderland of gaming and one day you’ll open a retirement home for all us gamers who can mix and mingle and play throughout our golden years.)
