damn thats way too long. I still backed it but i hope it will be a 90-120 hour game with 3-4 players after rules explanation.
I think play time will decrease with experience. First time round you need to learn and remember the rules, later play throughs will be a lot quicker.
Ant Lab Games said in their play through that they can get a game done in about 90 to 120 minutes. I think the video was longer because of them explaining to us what was going on.
