I had the chance to play this game over the weekend, and LOVED IT!! Gameplay, graphics, sound are all top notch with no glitches anywhere (that Ive seen so far). This is one of the only games that I can say equals (or maybe even out-do's) the legend that is Starcraft. And one of the best things, you dont need a top of the line system to play it, even when you scale the graphics down it still looks damn good.
I was running it on a AMD 2400+ 512mb and 9600 Pro and it ran without any issues. Some reviews have dropped a few marks from their score for this games loading times, but as the Scarfies say down south “Get over it” – its worth the wait :)
