I haven't play any racing games on it yet but that was because I've been pretty busy with stuff. Those of you who do have 3DS's do you have any particular favorites besides the obvious that is mario kart? I'd like something more akin the NFS: Underground when it comes to customization.
I've never tried it but my friend is always playing NFS and Ridge Racer on his 3ds. Whenever I get a hold of it, though, only Mario kart is plugged in so unfortunately it's all I have an opinion on, but it is fun though, at least.
