I'm thinking about doing a tournament or several of Pyramid Arcade games. I have enough Pyramids and boards and things to support about 24 players in a tournament of Pikemen, and Pikemen is relatively fast, easy to teach, and the tactics and strategy are not to easy, but not to hard. So I was thinking of starting with that.
Martian Chess is another possibility.
A class/practice session on Homeworlds leading up to a tournament is also a possibility.
Any other ideas?
If we get a community started, we could even do a multi game tournament, with a different game in each round. (Powerhouse, Pikemen, Homeworlds, anyone?)
I also have a post over at BGG
