Since most iOS devices have upgradet to iOS 5.1. Some annoying things have been happening with Civ rev on the iPad ( I am not sure about iPod touch and the iPhone).
One of the new annoying things that I have recently been having is lag. Some times the game just freezes and then chrashes
Also the graphics sometimes become really cheesy when I zoom in or when I go into city panel mode
It does seem that the new civ rev has adapted and adopted to the new software but really hasn’t improved alot.
