Since my PC has conked out and refuses to boot, I've been picking my way through the PS3's fantastic library of exclusives.
Heavy Rain: Move Edition - I picked up the Playstation Move controller and a copy of Heavy Rain. It works as a fantastic drama and the controls add a lot of tension and immersion to the experience. It's worth at least a rent and a playthrough.
Uncharted 2 - wow. Imagine a modern-day Indiana Jones and you have Uncharted. This game improves on the original in every single way, and features some of the most spectacular sequences I've ever seen in a game (the train sequence. Wow.)
