For me F-Zero is the best racing game ever great graphics and sound.
But a DS version would be crappy I think because the developers would try to get use of the touchpad and that doesn't work with F-Zero
Nintendo devs are intelligent enough to know where touchscreen is useless
Look at Mario Kart DS. Touching the screen during the race does the same as pressing one button (the one that switches maps).
But it would be kickass to have some level editing mode utilizing both screens somehow!
