While I really like this game, it goes way too slow if people are trying to optimize, they are new, and there are five people playing.  This is what happened on Thursday making a game that should have taken 1.5 hours take 3.5 hours.  We didn’t get to sleep nearly early enough, and it made the game not as enjoyable when there was 20 minutes between your turns.  I think a more synchronous style gameplay is needed for this game to work.  That or faster players.
