DZhanI realize this is an old comment, but just FYI it's currently $15 on Amazon for JUST the base game, or JUST the expansion.. so $30 for both. And the latest drop was like 22 for both.
Dang it, I wanted this and even asked for it to come back -- but now I just glanced at Amazon and (with Prime) I can get it for 14. It'd be silly for me to get it here.
I believe the game can accomodate 3-8 people, not 4-7. A pretty good deal for both the base game and the expansion; I previously bought both as a gift for a friend for about $30.
