N64 Skyscraper

Skyscraper is a battle course in Mario Kart 64. The battle takes place on the roof of a giant skyscraper, making it possible to bump opponents off the stage. It is unknown what building the skyscraper is. There are several gaps in the roof, making it easy to fall accidentally and lose a balloon.

Appearance in Mario Kart Wii
This stage also appears in the game Mario Kart Wii for the Wii. In this course's Wii reincarnation, it was made larger in order to accommodate 12 players and the edges of the gaps in the roof became ramps on which players can perform tricks. Also, areas 1-4 are re-ordered clockwise instead of having 1-2 and 3-4 parallel to each other (based on players' starting positions) respectively and have become color-coded.

Official descriptions
Mario Kart 64
 * Manual: "It's a wild battle on top of the skyscraper! If you fall off the building, you will lose one balloon. There are no guardrails to keep you from falling, so don't speed too much. A highly effective strategy for attacking your opponents is to crash into them in an attempt to knock them off instead of relying simply on the use of items."

Mario Kart Wii
 * Official European website: "It's a long way down from up here, so take care as you race over rooftops. Don't get dazzled by those giant searchlights!"

Tournaments
In Mario Kart Wii, a tournament took place on this battle course, where the course was made into a race track. Players had to do a time trial around the track, while avoiding the Bomb-Cars from Moonview Highway. The control scheme was restricted to Wii Wheel users. It was the first tournament of September 2008, and it was later repeated as the first tournament of September 2010, the first tournament of February 2012, and the second tournament of April 2013.

Trivia

 * There are 4 numbers from 1-4 on the roof. In Mario Kart 64, the numbers are in the following order (clockwise) 1,3,2,4. The order was fixed in the Wii edition.
