Yes, because it's still a Spielberg movie and fantastic. I might not want to pay $20 for the DVD though. Would you want to see a 3 hour epic from the same crew, only to discover than 2 hours 20 minutes of it is basically filler?I don't see why it's silly. Would it be silly to grouse over a Spielberg movie starring a casting director's wet dream A-list that was only 40 minutes long?
Game length is only meaningful when it's full of meaningful content. If they couldn't put 60 hours of meaningful content into Stick of Truth but put 12 hours of AMAZING stuff in it, then that's fine. I think the real issue is that we shouldn't have to pay $60 for 12 hours... it should be more like $20-30. But all console games have an arbitrary price point because of market fixing.
