Says the guy who never 'bothered' with Starcraft.
Of course i played Dawn of War. When people refer to it as the 'true heir' of Starcraft (except for the single player, which was **** and one of the reason i rank it lower then the older game), i think it's implied there's some similarity between the two games, at least in spirit. Not to say it isn't a fine RTS (one of the very best actually), but i'm having an hard time understanding how you can like one without liking the other when they are so similar in nature...
I'm with Tale, DoW plays very differently from Starcraft. You have unit pop caps, strategic points, the quantity of DoW's 7 races over the quality of Starcraft's 3 and many minor differences, units and gameplay factors. Also, DoW does not have any air units.
