I've been playing a little gem called "Overlord" on the 360 (but is/will be available for the PS3)
Overlord is set in an unnamed fantasy world, where the player takes the role of a resurrected warrior known simply as The Overlord who has control over hordes of gremlin-like creatures known as "minions". The player must defeat seven corrupt ruling heroes in order to re-conquer the lands and establish his lordship over its inhabitants. The game features a corruption feature, allowing the player to be “evil†or “really evil," where certain actions and choices affect different aspects of the story and gameplay. While the Overlord is controlled in a third person perspective, the way minions are controlled brings elements of real-time strategy and upgrades bring those of role-playing games The game also uses black humour and often parodies and satirises traditional fantasy settings and plots. (thanks to Wickipedia).
It's an overlooked classic and is definitely worth playing, if only for the antics of the minions!
