There making a star fox racer game. Which the game sounds prettyamazing to me.
I'm sure they would make a pretty good MK9 game too, we would probably see the game take a larger leap forward than we have in while. I'm not so sure though at what a team like Retro has to offer for a series like Mario Kart. I think the best use of Retro is for them to take series that needs a new way of looking at the series and to help transform it from there. I don't think MK needs that.
Dont want to be a drag, but thats a rumor.Please refer to it as such otherwise people will get confused.
Anyways, Retro wouldnt be doing Mario Kart 9, since I believe Nintendo would rather they do something their other studios cant do.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
