Yes the demo is godly and the devil arm is amazing.
I'm amazed at how a game that looks this good is considered to look unimpressive... you can't expect every freakin game to look better than everthing else. Just cause there are a handful of better looking games doesn't mean this looks 'meh'... graphics standards are going crazy.
I dare anyone to find a game that looks this good and runs this smoothly.
Thanks to Blacksaber for the sig!
