Mario Kart Wii recently, taking the time to carefully analyze the differences between this game and the installments of old. Following this, they wrote a five-page preview on the game. We've read the whole thing (omg no wai?!). We're excited.
First of all, each racer now has a plethora of rides to choose from: three karts and three bikes each. These are available from the start of the game. Also, the CC classes return, but with a small twist. The 50CC bracket is for karts only, the 100CC bracket is for bikes only and the 150CC is a mixture of both. IGN notes the difference between the two as the bikes having a tougher time with turns, but being easier to boost with (tip the wheel back to do a wheelie, hold it then zoom off). As for karts, they'll get boosts from powerslides, providing more boost depending on how long the player holds it, eliminating the need to slam on the d-pad to generate these anymore (we're not sure if this means no more snaking or not). Stunts will also provide boosts, allowing a player to perform a mid-air stunt off of a jump and shoot off once they land on the track.
