That copy of Xenoblade was actually from a store called McKay, though. Most of my game shopping happens there, although a good number of games this time around came from Gamestop - mostly from the same transaction, wherein I used a discount coupon and renewed my membership thingey in such a way that it paid for itself.

McKay tends to stock a lot of things for super-cheap; I've seen Metroid: Zero Mission for six bucks, and the occasional uncommon NES game for two or three. Pac-Man World was "very scratched," hence its much lower price point. Seems to work fine, though.

Depends on the genre. As far as action titles, the boss music to Mega Man 3 still gives me the chills sometimes - probably my favorite track in that entire series (with the Shadow Man music being a close second.) The boss music in Kirby's Adventure from the penultimate fight - the one against that giant orb - is pretty spiffy, too, although you really need the sound effects to give it the full context.
