Its easy enough to kill a save file, a mate killed mine the other day by simply chucking in the mem card with the RL save file after the game had loaded then the first time he tried to save it overwrote the thing, since the overwrite question comes up so often he just ignored it. Doesn't really bother me since my PS2 version is just for multiplayer, if someone killed my PC save file then I'd have the shits.
