It's true that the tracks could use more gimmicks, but a lot of Mario Kart tracks suffer from the lack these as well, except a few ones. ASRT has the transforming as a gimmick, which brings me to another point:
I was worried whether the Air/Water sections will take the majority of gameplay, this is a "Kart" racer after all, but watching the Panzer Dragoon track, it only had 2 transformations in the whole 3 laps, and they were brief, and most importantly, looked really fun.
Did anyone notice you can fire the "Ice" weapon both infront of you and behind you?
