It's awesome that you can play splitscreen. Not many games do allow online splitscreen anymore. However there is one issue. My fiance has her own GT and you can't go to the locker room when you are the second controller or move around the options with it. I think you should be able to do this when you have your own GT and aren't playing as a guest. That's all I have to say about that, but thanks again for letting us play together on this awesome game!
you should be able to once you get into an actual game lobby. 2nd control will highlight text in yellow.
It sucks that the guest account can't at least access the main account's custom classes Some of the default classes are damn near unplayable. (assassin without gold armor?! what?!)
