Do you think it's common courtesy for people to wipe their saved games before selling them? And do you delete your saved file before you sell it or do you just think eh whatever?
Do you think it's interesting to see where someone was when you buy a new game and they didn't delete stuff?
Do you play on their save file sometimes just for fun?
I don't really care either way but I do think it's interesting to see where someone's been. I've only had this happen on a used copy of Golden Sun the Lost Age that I received for Christmas one year
