I also played Baldur's Gate (awesome game, almost goes without saying) but did not name my character Rockman. That name I got from a couple of my college friends when I was taking a bunch of geology classes - that was one of my majors for a couple of years. It's also what Mega Man is (or was?) known as in Japan, Mega Man is pretty awesome too, so one more reason for me to use it. =)
