Ridge Racer 3D is one of two racing games available for the 3DS at launch, and since the other one is part of GameLoft's Asphalt series, there's really only one choice. 

Ridge Racer 3D's overall goal seems quite clear -- to use the visual perspective of the racing genre to be the prime example of the 3DS' 3D gimmickry. It almost seems like creating a decent racing game is a secondary goal, so it's quite some pleasant surprise that Ridge Racer is quite fun, too.
