You can mouse look at any time by holding down the right mouse button. Peeking in to any characters inventory is as easy as right clicking on a box in their character slot. Spells are categorized by their school of magic, which makes spell browsing easier than sorting through a spell book containing an unsorted list of spells. Characters will also auto-switch weapons during combat depending on if they are at range or in melee combat. These features make it perhaps the most refined interface I've seen in a 3d RPG to date.
Combat takes place in turn based fashion and is entirely in the first person viewpoint.
You are allowed to select between classic turn base mode or continuous mode. Continuous mode will keep the action going nonstop. Whatever actions you select will be executed at the next available combat round. For the most part I like the combat interface. I do have one gripe.
