Shy Guy Racing

 Shy Guy Racing would be a racing game published by Nintendo for the Wii U and 3DS that would serve as a spinoff of the immensely popular Mario Kart series. The only difference would be that instead of a roster full of different Super Mario characters, the roster would consist only of different Shy Guys, which are a species within the series. However, there will be more than just cosmetic differences; the game would incorporate interesting gameplay/level design mechanics, and would be similar to Sonic and All-Stars Racing Transformed, because choosing different characters would have a definite impact on your gameplay experience through things like exclusive power-ups.

Characters
As I mentioned before, the roster of Shy Guy Racing will be exclusively Shy Guys, but this will not mean that all characters will be the same. The most distinctive feature of a Shy Guy, the way I see it, is its color. Since color is the primary thing that differentiates one Shy Guy from another, this will not only be the factor that creates the different characters, but also the one that influences the characters' stats and power-ups.

It should also be noted that almost all the special power-ups are actually existing power-ups that all the racers could potentially get; however, this does not reduce their usefulness, because the special power-up of any given character effectively doubles the likelihood of getting a particular power-up during a race. For example, if a given player gets the most use out of green shells than anything else, he/she might want to choose a character with a green shell as their special power-up. This way, he/she has double the chance to get a green shell at any one point in the race.
