I also got to play a demo at BGGCon . We had 4 players , all completely brand new to the game , and we went through a round and a half in about 30 minutes the demo was set up to give us a feel for the endgame and omitted a few things like investments . Since the full game itself is only 6 rounds , I ' d estimate a firstplay would clock in a little over 3 hours and subsequent plays would be in the 90120 minute range . This can vary a little because each round can have a different number of turns . Also , I don ' t feel that adding more players will significantly increase the play time . Sure , there ' s more negotiation involved , but the offercounteroffer phase is pretty well streamlined to handle that . It was fantastic . I preordered as soon as I got home .
