It's very frustrating lol.
Not in a bad way, but I just suck at it, even the medium tracks, god alone knows how I will get on with the harder stuff, it's at that point in previous games I have traditionally called it a day and never gone back.
There's also a few niggling little changes like the way tracks are now unlocked vs previous games that make it more of a grind, but I still love it, but hate it in equal measure too.
