London Philly have take some of the best (and some dubious) game tracks and recorded them with the full orchestra... Some of them will be damn good but others I'm not so sure about.
Also when it comes to the choice of tracks I can agree with some of them but where are the older more epic pieces from the likes of Half-Life and Homeworld? Games that had music that truly helped you get sucked into the story but then again that's just IMO.
