The gameplay is totally different from NWN, and features real time combat with motion captured animations performed by a master of medieval sword combat. There is also ragdoll and rigid body physics, which allow for pushing of barrels for example. All actions in the game can be done with only a mouse though you can configure keyboard shortcuts if you want. Basically you setup different combinations of offensive and defensive moves and spells, which depending on how well you execute them during combat, will determine how much experience you get. There is additional feedback during combat to guide you on how well you're doing by telling you such things as you're going "too fast" or "too slow".
