Inspired by the contest at http://siegestones.liveoakgames.com/contest.htm, I am working on TCP 6. TCP 3 and TCP 4 were submitted to the current About.com design submission, TCP 1 and TCP 2 to last year's. None of them have been sufficiently playtested, and all need minor to major overhaul. I am hoping to give TCP 6 a good playtest before submission.
TCP = Tri-colored pieces. Mostly abstract games based on blue, yellow, and red pieces.
TCP 0 (aka Mugwump) ... I should really get back to that one of these days. It is the only meaty, not entirely abstract, one.
