Command and Conquer 3...
Star Craft II...
Star Craft looks a little childish to me... "cartoon-ish" if you will. But I have also grown up with the Command and Conquer series along with Dune 2000 as well. I'm a Westwood Studios kind of guy.
Blizzard makes fun games and has been going at it a while too with War Craft and that series, but I personally prefer the "Oldies and Goldies"... I'll stick with Command and Conquer. And, just because I prefer C&C, doesn't mean I won't play with you guys online with the new game.
On another note... In the last Star Craft, there was a hidden level where they were making a "Hybrid Race"... Any info on if they are included in this one? I believe it was something like a Zerg / Protoss mix.
