why not? if people see the game, play it, and think 'holy shit who did the music for this?' and then proceed to become fans of the band, I dont see a problem with that. You can't be elitist to potential fans simply for the fact they might not have had the opportunity to be exposed to the music before..
I'm sure SA would love to know people can get into their stuff all kinds of ways.
P.S. (I'm doing alot of P.S.'s today) - I hope SA has more taste than to make a stupid game such as that Revolution X one. I love RPG's, and if it happens to be a good one I'll be very pleased to add it to my collection.
