Hm. Had more sealed games than I realized. I didn't even know I had some of these! Some I just recently picked up. The collector in me bought crappy XBox games for cheap, but the gamer in me kept them sealed. I have a lot more that I opened and played once. Of the 225 or so xbox games I own, I'd be willing to bet that with at least 175 of them, I played once for less than ten minutes.
