Hi!! i just got mi PS3. my and my flatmatte are playing Assasins creed, GTA IV and Call of suty 4. The problem is that we want to play our own game, not overwriteing the others progress. I dont know if im clear in my explanation. Example: I started playeing Assasins Creed. Played for 4 hours. Then my friend played, but didnt know ow to create another user. And then how to save 2 diferents users of the same game. Its that simple and silly. Please help

If u sign in under a differnt usser acount it creates its own data for that user so U should have ur own account and let ur flatmat have his own one therefore u dnt overwrite each others saves. (u can create new usser accounts on the main menu of the PS3)

Thx so much man it was very simple but was killing me. Now verything its ok
