Uncharted 2: Amongst Thieves

I'm a huge fan of Naughty Dog and this doesn't disappoint. It's a cracking adventure from start to finish. The cutscenes are genuinely enjoyable. It does everything a good sequel should. Building on the first game but making everything better.

Personally I'd rather not have AI companions for quite so much of the game and I still think the puzzles are a bit too few and far between but other than that it's hard to fault.

Some brilliant set pieces and strong level design maintain your interest all the way to the end.

Personally I have to say I think Batman: Arkham Asylum probably just shades it as my GOTY but it's a close call.
