I'd like to know what people think the hardest and easiest tracks in the game are (including addons tracks). Here is what I consider to be the hardest and easiest in the game.
Hardest tracks:
* XR591 - all of the sharp u-turns make this somewhat challenging
* Minigolf - probably the only track in the game where it's actually difficult to complete every turn without coming to a stop
* Down by the River (addon) - although the track itself is very easy, this is one of the rare tracks where the AI actually knows how to drift and if you're playing on time trials, good luck not coming in last, even if you make no mistakes.
* Mountain Village (addon) - track is very narrow and has several sharp u-turns. I think it's impossible to complete this track without coming to a complete stop at least 2-3 times.
* Nolok's Factory (addon) - broken in 1.0. One path requires you to complete a very sharp turn while going very slowly because you're driving in a wooden crate. The other path has a minecart which is guaranteed to hit you no matter what, and if you mess up and end up crashing into a wall, it takes a bit of time before you go back to full speed.
* The Cube (addon) - two paths, one of which consists of the longest turns in the game (spirals) and the other consisting of sharp u-turns. Since the two paths are all locked in a cube, it is hard to tell who is in first and last place. Think N64 Yoshi Valley.
Easiest tracks:
* Shifting Sands
* Hacienda
* Ravenbridge Mansion
* That one broken mystic addon in which the AI gives up and gives you a free win.
* Amazonian Journey (addon) - very easy although the two paths are broken in length to where it's obvious which one you have to take to win.
* Art Museum (addon)
* Canyon 42 (addon)
* High in the Sky (addon) - since there are a few speed boosts and the AI never uses them, you're guaranteed to win every time.
* Mod Circuit (addon) - I think this was supposed to be some kind of tutorial track to resemble the Luigi Circuit tracks in mario kart.
