I stopped with AC: Brotherhood.. But this game tempted me and I regret it as well.I also haven't been able to have a trouble free play session since I bought the game earlier this week. I hadn't purchased an Ubisoft game in a while because of their DRM and general customer care. Anno 2070 tempted me to give them a chance and now I am regretting it. I probably won't buy another game from them until I hear they have changed their ways.
