I just beat it too, and I must say, the entire game was freaking awesome besides the shite ending. I facepalmed when the narrator repeated the "War never changes" line. It's like Bethesda were trying to put some meaning into the game's story, as if it's taught you a valuable lesson. The opening...
Foo Fighters - X-Static
Wow, I've just started properly listening to the very early Foo Fighters, and I must say, while it's completely different, it's absolutely exceptional. This song has an awesome riff.
Goddamnit, I didn't think I'd care for this, but all master recordings? I suppose I'll have to take a look. Monkey Wrench, Killing in the Name, Laid to Rest and Free Bird FTW.
Fallout 3 - 9.7/10
FINALLY got this today, I've been missing out on a lot. Runs brilliantly on maximum, and plays even better. I haven't been this immersed in a game since, well, ever. Half Life 2 doesn't come close (don't kill me).
