Mine would quite possibly have to be the Streets of Rage series. Best music ever. On a side note, if anyone really likes all sorts of video game music, my friends brother runs a video game music radio located at www.vgamp.com Half Life 1 and 2 also had some pretty serious tunes as well... but Streets of Rage (1 - 3) for the Genesis was by far the best Whats your fav? EDIT: OH YEAH! The original Doom was awesome as well.
