I tried to log in with a different account with PS3 (not yet registered), but the login ID filed is grayed out. So my question was if we want to play using the same PS3, would inserting a different disc allow logging in with a different account?
Yes, if you wish to use a different account, the other person has to have a separate subscription and must have purchased the game separately for each platform that they wish to access it from. It is unfortunate, and it would be nice if SE had an "upgrade" fee to add an additional platform, that was significantly lower than the actual cost.
