Before I looked at the list, I was thinking "most the XBOX360 games I either have on the PC or are available to me on PC". After looking at the list, I discovered I was right. They look better on my PC also.
I'm really going to have to try MGS4 and Uncharted 2 sometimes because everyone is making a big deal about them. However, if it ends up playing like a long movie with unoriginal gameplay in-between, I will be seriously dissapointed.
