The Thief series has done amazing music imo. http://www.thief-thecircle.com/media/music/ you can download it!

:goodjob: I want to play Ristar again.

http://www.youtube.com/watch?v=1i8vY4jzzZI&feature=related most of the music in the game is actually really good but i'll just post this one.

http://www.youtube.com/watch?v=42u0KB6f5eU. I post this every single time a theme music for games thread pops up. Also, many of the other songs in the game are really good too but i'll only post this one.

People posted others so I wont post them, and I wont post entire OSTs, even though some deserve it.

http://www.youtube.com/watch?v=ca4j4cQPcJ8 (good game, check it out if you havent, underrated imo).
http://www.youtube.com/watch?v=pG0wVbwGYWo Amaziong music for an amazing game.
http://www.youtube.com/watch?v=sZViMbs_wrE Its not the main theme, but damn this REALLY had impact, especially given the timing and the mission objective, and everything, really great job by bungie, the music played a big part.

Oh yeah I love that song.

I always agree with anyone linking to The Circle.


As for me, I'd have to add: http://www.youtube.com/watch?v=26I-Pw-yPJ4

To post something I didn't see posted yet and love, the http://www.youtube.com/watch?v=--rxf-28YlQ.

Call of Duty 3: http://www.youtube.com/watch?v=_fr4iZnovAQ

Team Fortress 2: http://www.youtube.com/watch?v=dRDmirJATKs

And obviously the Skyrim and Morrowind themes. Can't think of any others off the top of my head...

http://www.youtube.com/watch?v=DSbTviFhHI4 have an excellent title theme.

Aside from Daggerfall and Morrowind, of course:

http://www.youtube.com/watch?v=YXd6MeIOuyA (both the original and Warband)

http://www.youtube.com/watch?v=mhu9FugJ88Q

http://www.youtube.com/watch?v=yPdL2nSuiYM Not sure if this is considered the 'Theme', but it's the song that I associate with Arena, and I love it. :wub:

P.S. (Again, I want my old /wub/ back)

I forgot to mention http://www.youtube.com/watch?v=SHtDvXU10Wg&feature=related.

I agree, the music blew me away when I heard it. Poor Oblivion, your truly the ugly duck of the series, except there is no happy ending and you don't turn into a swan.
Edit
Will list some more of my favorite later.

Ones that haven't been mentioned yet. Some armored core ones,

Never played it, but if any video game deserved to be made into a movie based on the sound track ONLY, that game would be on the big screen already (the entire soundtrack is just plain EPIC (my 2 cents).
