3r4nd0n The reason grid city is unique is because it is all grid, and a track that uses only grid (that is actually good) is very rare. I agree that the mythical mountain collab isn't unique at all, but I've never seen the way you turn around on spikes used in any other levels. That's the only unique thing about it. And I really do think that Magnum Opus has unique parts. I don't have time now, but there's a lot of clever stuff in that track.
I'm not telling anyone what to think, I'm stating my reasons for not putting the tracks into the first post. Everyone is free to post tracks they think are unique, I'm just putting the ones I find most striking to me into the first post.
It's my thread. I didn't say this list is the end-all for unique tracks, just a cobbled together list of tracks submitted by others players that I found to be both unique in gameplay and fun.
