The MCDM RPG, it's not out yet. (Patreon backers have access to playtest documents, but I'm not that dedicated.) Also it has a name, we just don't know it yet. No, I'm not salty about that.
"Bite Marks", a PBTA game about werewolves. Just hasn't been the right time yet.
Savage Worlds variants include Weird War II, Weird Wars Rome, Last Parsec, Legend of Ghost Mountain--in each case, I only have limited game time, so there's just a big old backlog, you know?
