The interface itself is fair, though it does have a tendency to get cluttered very easily. However, with a little organizing, essential items can be retrieved quickly. The function keys are used as hotkeys, and that can be a lifesaver. In short, it's not a very intuitive control scheme, but it can be learned with minimal effort. I can honestly say I have no complaints with Revenant's graphics.
Characters animations are superb.
The backgrounds diverse, quite colorful, and nicely detailed. The spell effects are excellent, and make use of some exceptional lighting. Revenant will rarely leave you without something to see. Sound is exceptional as well. Voice acting is generally quite good, and consistent with each character.
