C&C 3 is pretty freaking good. I got it two days ago, and I'm real impressed. Admittedly, the missions are a bit easier then I hoped, but they're still great fun, and the graphics are great, even though I had to turn it down so my comp could handle it.
Westwood have done it again! Although I must say I don't know why they swapped the left and right mouse buttons around (as in, right moves/attacks, left cancels) because I wasn't expecting that. Still, if that's the worst thing I can think of, it must be pretty damn good.
