Received my copy from Amazon this morning. I'm liking it so far. Only few gripes is really just with the steering, even setting the sensitivity all the way to the lowest, it's still awkward at times to keep a smooth turn going. Also I really don't know whether to play this with the 3D on or not, I find the game so much smoother (running) with it off, and do find it a little easier to control, but it does look quite nice with the 3D on.
Something I've just noticed, and not sure if it was doing it the whole time, but when I turn the game on, the 3D turns off (as in the 3D green light on the 3DS) and will only come on when I enter the race. For all the menu's and such it's in 2D. Does this happen to anyone else? Is it maybe my game or a setting I accidentally changed?
Also if anyone still plays, I'd love to play some online sometime.
