I'm gonna be in the SF area for two weeks starting next week, and while I'm there I wanna check out some of the retro gaming stores that I've heard about there. I'm not interested in the usual places like Game Crazy, I'm looking for stores that might have old factory sealed games, from the 16BIT era onward. I've heard there's quite a few stores like this in the SF area, so which ones should I not miss?
