just wanna say that this game is GREAT and easily my favourite of the launch lineup.
graphically it is disappointing, i'm not gonna lie (though it does have its moments), but this is made up for entirely by the sheer haptic bliss that is the 3DS circle pad, which may well be the greatest ridge racer control mechanism yet devised - seriously, they could've released a 3DS with a playstation control lead sticking out the back for the first four games and i'd have dug it more than the negcon. why? because it strikes the perfect balance between giving you analog control (which is what you need for racing games these days) and maintaining the responsiveness of a d-pad (which is what you need for ridge racer). also the course selection and music etc are as good as you'd hope for, so yeah, if you like ridge racer or FUN i highly recommend this game even though its qualities have absolutely nothing to do with the effort that has evidently been put into it.
also it doesn't delete the data if you beat someone via streetpass, you can always go back and beat them better.
