I don't have a lot of turns into the demo, but 4-5 hours in and so far it plays like Civilization IV to me. At least in the 'barbarian' sense, lol I keep getting my ass handed to me by Warlock's version of them. Those vampire units are brutal! I haven't figured out if I can build other units. You start out with a ranger which is like an archer, but I can't seem to build them again.
