Playable Characters overwrites the game! (PS3)

I just completed the game too! had one more mission which was the Mary Jane Thrill Ride which I decided to leave for now, so I thought I'd have fun with the symbiote.. and it never accurately said that it'd overwrite the game!!
This made the completed game data corrupt later on the PS3 Game Save Utility.

Glad I didn't get the Collectors Edition, otherwise if I played as New Goblin, it would have done the same thing!

Pointless! pooft.
