Well, since this is the topic these are the games IMO that rule soundtrack wise.

-MK2
-MK3
-MK4
-Some of the music in MK:DA
-MK:D
-Donkey Kong Country Series
-Perfect Dark
-Goldeneye
-Tetris Attack
-Faceball 2000
-TNMT 4:Turtles in Time
-Boo Boo Bop
-SF II
-Psi-Ops:The MindGate Conspiracy
-Mario-classic marios and the new one for the DS
-Zelda games
-SSB games

any metal gear solid.
any silent hill.
can't go wrong either way!!!

Some of my choices:

Resident Evil
Silent Hill
Dino Crisis
DDR (Very different, I know - but they have "boss" songs too.)

First thing mentioned should have been Castlevania: SOTN

You can't honestly make a list of these and not include Tekken 3, Tag, and 5 and Soul Calibur 2 and 3. Those soundtracks are incredible.

Jerrod has just given me permission to use the link I chose, so let's begin. First off let's start with Opening Themes. Everyone gets two nominations max. I'll let nominations continue until tomorrow night, and then we will begin voting. Please give the game name and song title of possible, and a link to the song. If you don't know how to do it, ask me and I'll assist. To play the song, go to where it says to download the song file and hit click here. The link we are using is this:

I'll just throw out some to begin:

OPENING THEMES - Nominations (These only include the opening to the major part of the game, not arranges or anything of that sort.)

-Prologue (Dino Crisis 2)
http://gh.ffshrine.org/soundtracks/556/1
-Outbreak Main Title (Resident Evil: Outbreak)
http://gh.ffshrine.org/soundtracks/2379/15272
-Martial Symphony Opus 5 (Tekken 5)
http://gh.ffshrine.org/soundtracks/859/21
-Reflections (Silent Hill 2)
http://gh.ffshrine.org/soundtracks/107/1

Guilty Gear series pwns all.

Come on, I need actually songs. Just go to the link I gave you, look under the letter of the title of the game, find it, and try to find your song on the playlist.

how about the the twisted metal series (just cause of rob zombie) and THPS (tony hawks pro skater)1 and 4 and THAW (tony hawks american wasteland)
