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. Sound effects really shine.
Battles are almost more vivid to listen to then look at.
Creatures snarl and stomp with exceptional tone, and spells rumble like thunder. Let's just say there's as much to listen to when you're losing as when you're winning. SoundBlaster owners can still enjoy the game, but it involves changing one of the .ini files. Regrettably, the other necessary ingredient in any RPG is somewhat lacking. Revenant's story is mildly amusing at best.
