Which Warhammer 40k?
The tabletop game?
The books?
The comics?
The movie?
The FPS?
The TBS?
The squad-TBS?
The RTS?
Or are you refeering to the future installments?
The MMO?
The TPS?
Yeah, Warhammer 40k is a pretty big universe and it's arguably where Blizzard took it's inspiration for Starcraft (since the tabletop game predates the RTS and there are many similar races).
I recommend starting with the Dawn of War series. Both 1 and 2 are pretty good, but different. DoW 1 is a base-builder RTS in which you control upgradable squads, while DoW 2 is a more tactical squad-based RTS, where you only control certain squads, each with it's own special weapons and abilities. DoW2 is more tactics-oriented (borrowing very much from Company of Heroes) while DoW1 is more mindless RTS fun.
