The Dark Messiah skill system...
Ubisoft releases video of the Dark Messiah skill evolution system
Dark Messiah of Might and Magic will be a source engine game from Ubisoft that brings the combat, might and magic of the turn-based game universe into a first person environment. Dark Messiah promises an rpg-esque skill system with solid physics and immersive combat that will allow players to tailor the character into any direction they want.
You can concentrate upon the stealth skills of the game, learning to backstab and hide in shadows or plumb for a melee monster. If you want to tailor your character to a powerful wizard, once again you can.
How? Simple: the skill evolution system.
