Personally, I'm not really a car guy. I'm more of a driver. I don't really have a strong preference for what cars are in the game, I just want a large variety of types of cars and a large variety of tracks. So while it's nice that Senna's kart will be in the game, essentially its just another kart. I'm much more excited that one of his F1 cars will be in the game and even more excited about the different track variations. However, I will be pretty disappointed if Interlagos and the Interlagos Kart track are not in the game especially since they are part of the opening intro to GT6.
