When you complete Parasite Eve (PS1), you get to take a single weapon with you and play through the whole game again (with an epic alternate endgame dungeon). Right when I beat the first playthrough and it was saving, my dog came running through the room and caught on the controller cord at such speed that it ripped the PlayStation out of place and sent it sailing. The save file was corrupted. I didn't wind up beating new game plus until 10 years later.
