I fucking love video game soundtracks, from their inception to today. There are so many video games I've plaid that I don't think I would consider complete or good experiences without the soundtrack.
Please post links to good songs from video games in this thread.
One of my favorite songs is from Lufia II on the SNES: https://www.youtube.com/watch?v=WkwHKKWpoaE
I've been playing Mario Galaxy again, and it's both the best Mario game and has the best soundtrack of any Mario game. Very majestic.
