I can't believe they castrated DoW like this. The campaign is ONLY for the marines? WTF? No base building? Can only have like 4 squads EVER? They should've released this game as something else, preferably on a console, and made a REAL DoW2. There are a lot of us out there that don't play multiplayer, meaning we won't really get to play with all of the other races as extensively as we do the stupid humans. They finally add the 'nids to the DoW universe, but remove the DoW game. Fail.
Did you ever play Dawn of War? The first one? The campaign in that was only for the Space Marines - aside from one or two occasions where some Imperial Guards troops were assigned to you, it was nothing but Blood Ravens the whole way through.
As for base building - well, this way is a lot fluffier. No base building in the table top game.
I quite like the style DoW 2 has used - it reminds me of Warhammer 40,000: Chaos Gate in some ways. My main complaint is that it becomes very repetitive quite quickly.
