All the best single race tracks cut from BnG, focusing on original layouts and abandoned early environments. For the racer - not the completist!

Severely unfinished tracks and prototype / drag / drift / 2280 tracks were left out, and "repeat" tracks (versions with identical layouts and similar environments) were cut down to the best examples and repeats with drastically different environments. All legacy tracks have value, but some are just more interesting as curiousities and records of how the track change than they are to race, especially against other versions.

Honorable mentions:
Utah Project 0.1, for being a tiny little devil of a track that just doesn't fit in with the rest,
Ishtar Citadel 0.2, for being a ton of fun to race but like 90% unfinished in the environment
Zephyr Ridge 0.3 for having 100% of it's environment while 0.5, though definitely better, is frustratingly missing a bit right at the end!
