Dawn of war isnt only about gameplay, story and HD graphics. Its also about how it absorbs you into the world.
Space marines sound good, nice quotes and buildings look like something you would actually just deploy in the field, I really like units arriving by drop pods or planes.
Eldar look very ... eldarly ... I am sorry I dont like eldar at all, I cant talk about them nicely, but the point they disgust me even here means they are well made.
Orks, how I hate xenos and orks in every game, they are so boring ... but DoW3, now thats something, I finally love orks, they are so funny, entertaining and actually feel like orky orks. They are awesome, you did really amazing job on them.
And here Id like to express my hopes and expectations for future races. I hope we get more this ork quality content.
I hope when chaos arrives, we will get half mad space marines randomly roaring and screaming and asking if you hear the voices too and asking for new drivers . I hope they will get same tortured, bloodied and scared slave that will summon buildings out of warp and levitate them in air while slowly building them. I hope the buildings will have those small tentacles writhing and mouths on walls screaming.
I hope when The Hammer of the Emperor arrives they will have badass fanatics that are ready to carve you in half while realizing they are going to die before they even reach you. Psychotic psykers with barely understandable mumbling before either your or their head explodes.
I hope when Tau arrive they will bring all their fancy, glowing, shining, clean buildings with them. Lot of mini-mechs with mini lasers and devotion to greater good.
I hope you get what I mean, I could go like this for hours. No need to hire some hollywood actors to say something as long as quotes from units already sound cool by standard and no need to pump 711738x anti-aliasing and play it on 8k to see every scratch on building, if that building already captured the idea of given race.
I hope the good work will continue and that art spirit we see so far will stay with the game.
