For some reason I just can't muster up a lot of enthusiasm for Starcraft II: Wings of Liberty. I don't tend to be too hot on multiplayer in the first place, and paying for just a short Terran Campaign feels kind of lame. Plus I read that all the units/structures are incredibly fragile, thus making the battles over with super-quick. That was one of the things I really loathed in Command and Conquer 3, so I'm probably not going to like it here either.
If I even do get it, I think I'll wait with this one until it's offered as some sort of discounted package with the other two they're going to release.
(I hear the editor is great though, although I don't think I'll be crazy enough to start another TTBE project with it any time soon)
