Best RPG to date.
Graphics are on par with other titles being released and look beautiful. I have mid level hard ware 2ghz cpu with ATI x800xl video card and I can play 1280x1024 with most of the pretty features turned on.
Sound is amazing. Real world effects will have you looking over you shoulder from time to time if you have a 5.1 setup. The random and soemtimes not so random chatter of citizens on the street gives a very "real" feeling to the cities.
Gameplay is fun. Seems a bit too simplisic but the bottom line is that a game has to be fun and this game definately is.
