So as the topic states, is this game a Civiliztion meets Warhammer 40K: DoW mishmash?
I don't see any DoW here unless you mean setting. Looks pretty much like Civ5 with a 40k skin to me. Makes me happy enough to give it a try, but I fall firmly in the WH40K fan bucket. EDIT: Oh yeah, Civ5 minus any diplomacy at all. Zippo, zilch, all combat.
Might want to check this out. Stupidly long, but shows a ton... https://www.youtube.com/watch?v=kjekq8IB468
