Well, I decided to take a bit of a gamble this MTC while honouring the recent Trackmania Grand League, which recently finished its beta season. However, the entire track I made from scratch, using footage from the TMGL to help design the signature elements which appear in the map. Only one signature element is part of the main route (with a route should you fall off letting you get back to the main route) while the others serve mostly as background elements, although most do allow you to try and drive it if you want to have a taste of what it was like.
Note that I do plan to add in some more Mediatracker elements so that the signature elements are properly credited in-map, but for the time being, the signature elements which appear in the map include:
Eurosky's downhill chicane (as part of the main route)
Airbridge's... Airbridge
Betwinners' Blimp Jump
The mushrooms from Mushrooms
The forest of poles from TheForest
The boost platform jumps from a map I can't remember the name of fully
The palm trees on grass and cactus on dirt from two other maps which I can't remember the names of off hand.
