Just finished Enslaved and Splinter Cell: Conviction.
Enslaved is gorgeous and has neat characters, and the gameplay isn't bad ... but the stuttering framerate was pretty disappointing.
Splinter Cell has some neat gameplay mechanics, but I found myself getting frustrated during the story mode since it's kinda linear, kept getting killed in IMO poorly designed rooms. On the flip side, I'm playing the 'Hunter' game mode now, where it's just about clearing out enemies as efficiently as possible (no plot), and it's a lot more fun. More room to breath, and games always seem better when you do well at them.
