I didn't know if I should put this here or in base game but I thought I could be fun to see how fast i could get all the stats for a skater or a custom skater on with all the levels unlocked, although i could see it with new game but I don't know how different from any% it would be i could also see no stat change and one where you can add to your stats

It would 100% be a category extension, so you are in the right place. If you complete a run, show it in the Discord and I can make a category. We don't make categories without runs.
