Best RTS since Starcraft!
I enjoy the RTS genre, but so few games employ the futuristic theme, and the ones that do seldom do it well.
I found the races to be well balanced, and quite varied. Enjoyed the space marine campaign (reminded me of Terrans in Starcraft). However once you get used to Chaos, you love the evilness of the race (remember infested terrans - just less work).
Also liked that this game can be played in short doses and quick rounds - handy for us older gamers that have jobs, wives, houses etc. I used to be a hardcore RPG junky, till life got in the way..
Anyways, great game. If you loved Starcraft (one of the greatest games ever), you won't be disappointed with this one.
