My PS3 was struck by the YLOD yesterday.
You've made me realize that I don't have a backup of saves from games like Valkyria Chronicles or, expecially, Final Fantasy XIII. Two games I've put some time in and haven't completed yet.
Though there was some good yesterday, I was able to eject Metal of Honor before the system went completely kaput. A $3 rental didn't turn into me having to buy that mediocre game.
