I really like this game and think it would fit in well with my gaming group, however, we often have 5-6 players. Someone local is selling their copy for $6. Aside from issues with two people having the same color, how hard do you think it would be to combine two games in order for GM to support more than 4 players?
I haven't played in a while, so maybe this is easier in my head than in reality. The rules would need to be modified for each turn refresh with more players, but there would be enough regions, projects, etc. to support it, and I don't find it to be a problem that cards will be duplicated.
