Played through the Mirror's Edge demo a few times.

This game was getting a lot of hype it seemed, and I wasn't too sure about the first person free-runner concept, but amazingly, it works brilliantly. Being in first person as opposed to third, it is really easy to get drawn into the game and develop immersion. You feel the gentle thuds of shoes when you are running really fast, hear the wind whipping past (especially when you fall to your death), and everything else involved in the coordinated movements. You can only see what she sees, so you really need to look around and find the angles, and despite the fact that most of it is colored in red, some of them are hidden rather well unless you know exactly where to look. Observation and quick assessment of the surroundings is still key.

The controls were a little awkward at first, but they fit really well after you get used to them.

I'll definitely be picking this one up when it comes out.
