Xxio from TeamLiquid wrote up a rather nice article on the importance of custom maps in the eSports scene, which any Melee mappers would certainly be interested in.
Galaxy 6000 by MiketheSspike
This map is a remake of the NES, 4 player racing game, Galaxy 5000, and includes all of the original 10 tracks and 5 vehicles. This project really reminds me of the old F-Zero games and maybe even Blizzard's own Rock 'n Roll Racing.
I want to see Jake Badlands, Olaf, Zeratul and Blackthorne racing against each other. That would be a nice Blizzard party. ;-)
