We've got GT6 and the Logitech wheel with our PS3. Of course, my BRZ is the game is tuned quite a bit… my husband kept his stock in the game and has fortunately gotten better at driving it over his regular WRX collection (I teased him for a while that we couldn't get the BRZ until he stopped hitting things in the non-AWD car

). When we finally get out of this break-in period, I'll have to turn off my additions and compare! (I'd never have the real $ to do what I do to my cars in the game…

especially as my favorite Mine's Skyline isn't even legal in the US…

)
edit: I know Jeremy Clarkson, when they were still allowed to play the GT games, used to say the cars handled quite like the real ones.
