I suspect Ubisoft has vastly different attitudes for different teams. You have the guys making the extremely fun, innovative, Rayman platformers, designing levels like this: https://www.youtube.com/watch?v=7m5YQrucis8

Then down the hall you have the guys chugging out Assassin's Creed 57: Nothing At All New.

That said, I'm an outsider, I don't know, but I'm wagering those vastly different games have vastly different types of teams behind them.
