I'm not quite sure what was “nail'd” here, but it certainly wasn't game design.
When most people think about the first time they came across a racing game, they recall an arcade style racing game such as OutRun, Crazy Taxi, and Ridge Racer. Over the past couple of years this style of racer has taken a back seat to the much more realistic Gran Turismo, DiRT, or Forza Motorsport. These are all well and good for people that like to get down and dirty with the specifics of a car, look at the engine, and kick the tires before they head out on the track, but what about the people that don't really care? What about the people that just want to jump into the first thing with go-faster stripes and tear up the track with their friends? That's where nail'd comes in. Supposedly.
