There are a lot of soundtracks I love. But the best soundtracks are soundtracks from "ye olde games"
Toonstruck
Lots of classical music in this game. A lot of gamers don't know that
The Dreamweb
Cool techno-style music. Nice cyberpunk sound. PM me if you want the soundtrack, I recorded the music from the PC version.
Novastorm
One of the best soundtracks I've ever heard in a game. Fast and suits the action on screen. Also recorded this soundtrack directly from the game. PM if you want it
Gabriel Knight
Classic adventure supported by a brilliant soundtrack by Robert Holmes
Quest for Glory IV
Went nuts when I heard the cool guitar solo's through my AWE32. Still one of my favorite Sierra games.
Final Fantasy VII
Best game I ever played. Great emotional soundtrack!
Golden Axe
Spend too much money on this game in the Arcade halls. Good thing the game was released on the PC
Monkey Island Series
What's not to like about Caribbean style music?
Other good soundtracks: Marvel Ultimate Alliance, Silent Hill 2, TLJ
