I'm pretty much the same as far as buying sticker-covered games. All the titles in my first post were either $1 or $2.50. For games that cheap, I totally don't care.
Something that is actually semi-valuable (when not all crudded up) needs to be relatively clean for me to be interested. If I end up tearing a label on a $1 game, then oh well. No big loss. I'm not trying to risk that for a copy of EVO or something unless it's like 10 bucks.
