I'm glad to hear sales are not slow. I thought you were saying otherwise, but I'm glad I mistook you.
I bought it the day it came out--also along with RE4--and I got the last one on the rack. I just assumed they didn't order that many, but maybe I was just lucky to snag a copy. As for it being on a handheld, I actually bought one of the NES GBA SPs just for this game. Of course, I read about the DS right after, and that would have been the better option. But, too late now, and I like my little GameBoy.
