I saw the demo of Red Alert 3, I was a big fan of Red Alert in the mid 90's, and i'm glad someone is tackling strategy with navel, Supreme commander did a fair job of it, but the ships were just too expensive and took too long to build to be of actual use.
I like the real time fluid physics in RA3, as well as te build animations, other than that, it looks dull, come on game developers, what are you doinf, all this power on GPU's and real time hardware physics rendering, should mean that they come up with something more to add to the game play, see in Ageia's pack for UT3 one map is fun because of a fairly random thing whirling around, a tornado that affects everything.
Spore is great because it tries to handle a whole galaxy at once, the creatures walk adaptively to how many legs it has and how they are designed.
I have so far created 3 strange races

lol that can only be described as alien
