GeekList: Icehouse Pyramid Games Sorted by Average Rating: "There's also the two-player 'binary homeworlds', which obviously doesn't involve the good-evil element, and emphasizes even more the particular strategies of the game. The only other rule different from the regular is that you only have 3 of each color/size pyramid available (so 3 small blue, 3 small red, 3 small green, 3 small yellow, 3 medium blue, etc etc). Andrew, who people remember mostly for the luck-fest that is Fluxx, prefers binary homeworlds because there isn't that element of luck in the regular game."
