IK games

I was wondering... 

Are you guys aware of any games out there, any at all, that feature an IK animation system?

IK =Inverse Kinematics,or in other words believable character animation - feet stay properly on uneven ground, when grabbing stuff, objects don't just magically hover in front of the character but instead look as if they're actually being held in their hands, etc...  

Um.... most games?

Seriously. Almost every game with 3D character animations has IK to some extent. They might not do everything you can possibly do with it because past a certain level of detail, it's just not worth the CPU time.
