Remove the loop tracks if they're still in (e.g. green loop, red loop, etc.)
They're really bland and CPU being stupidly fast on these isnt even challenging, it's just silly
And I'd probably remove 80% of the edgy castles
I probably sound like I hate CTGP now, which I dont lol
I would increase the amount of supported tracks from 218 to 268. That way all the retro tracks that were removed are put back in, and so there would still be room for new track ax
Hope I won't become biased with my decisions on what tracks get to stay and which don't.. (Probably let the community decide and make my personal favourites hidden tracks like Star Slope)
But before all that, I'd try to make Item Rain and 200cc possible on regular WWs.
