Uncharted 2: Himalayas
I got Uncharted 2 for Christmas and while admiring the flashback structure of the opening of the game the sucky console combat was a bit of a blocker for me for quite a while. However at the point that you are climbing the ruined hotel the experience was something else.
The game really felt like playing an action film, only a few cronky control moments over jumps detracted from the experience. The train sequence was equally cinematic but technically I loved the fact that there is so much variety in the scenery and that the transitions (bar the train tunnel) are so subtle. It’s an amazing feat of engineering.
