I created a second user on the PS3. My expectation was that within 2 player games, the second player could choose the second ps3 user, that way trophies earned get saved to that ps3 user and not to mine. Is this not the case? Or is it game dependant? We tried Wheel of Fortune but second player doesn't have an option to select the second ps3 user.
That is not a option
Whatever username you log on too that account will only be credited of earning trophies.
You would have to go back and re-earn them on the second account.
You also cant choose that second user account if you are playing splitscreen.
Thats atleast with the games I have.
Sony has left this feature up to the developers to implement if they so choose.
theres only a SMALL handful of games that support this
