Re:Boomtown as a 6 player game?
I would guess that the number of cards as well as too few towns would prevent this from being a good two player game. Also, the distribution after an auction may be a bit off. Saying this, there will be an expansion for this game, so why not email the guys at Face2Face and ask them if the expansion will include enough material for 6. Or ask Bruno Faidutti himself on his message board. He always seems ready and willing to answer questions about his games.
