Really? Seriously?
FPS of course. I don't know why you would think Gran Turismo makes driving sims a larger genre. There are two FPS games that can sell comparably to it, or possibly even more. There are also far more FPS titles hanging in the multi million mark than there are racing sims. Maybe if you considered racing as a whole genre you might have a point because of Mario Kart and most Need for Speed titles.
