Actual combat can be about as simple or as complex as you want it to be. We're fans of the classic "fighters slash toe-to-toe with enemies while spellcasters hang a couple spaces back and lob magical death" school of thought, and the fierce-looking animations and simple interface complement that approach nicely. You'll probably get a lot further, though, if you know how to exploit things like sneaking and flanking bonuses. You'll probably also want to learn the difference between a guisarme and a ranseur, because those are among the staggering selection of weapons you'll be able to choose from right off the bat. Really, the only things needed to make the classic D&D experience complete are some iron rations and a songbird.
