(from Valencia, Spain)
My latest game: Big*Bang, a simple abstract about the first minutes of the Universe
My best-rated game: Tetrarchia, about the tetrarchy that saved Rome
Title says it all. The game has to work with two players, but I'm not opposed to a 2-4 player game for instance.
Tetrarchia is slightly under $30 and holds 1 to 4 players. A cooperative game (with a competitive variant) about 4 Emperors fighting for the survival of the Roman Empire by the end of the III century.
