Great ideas you have put forward.
I was thinking about the idea of the extra cars the other night, im not sure how it would be possible from a racing point of view. What I mean by this is the hazards during the race. How do you send a hazard to an opponent that isn't numbered on the controller? Do we all buy new controllers that have 8 buttons, or can Real FX think of an idea to utilise the same controller to send hazards to opponents 5,6,7 and 8. Maybe double tap 1 to hit opponent 5, double tap 2 to hit opponent 6 and so on...just something to think about. Actually it would be nice if this suggestion had its own topic, ill let you create it since you asked about it first.
