Why is there All collectibles and 100% for ILs? They're pretty much the same and I don't understand why the same category is on there twice.
I don't see why you wouldn't do a no badge 100%. Unless you're strictly talking about ILs in which case some must be 100% ILs if a badge doesn't assist on a level. I'm not too certain if there are any because I don't do or really plan on doing badge runs.
Plus all collectibles and 100% are different in the fact that all collectibles is all flowers, yarn and stamps and 100% is finishing with all hearts as well. And since taking damage could sometimes be faster, some people might prefer all collectibles to 100%.
I think I see why they wouldn't do a no badges any% because there wouldn't be too much skill involved as compared to collectibles and 100%. That's why any% runs may be faster, but usually aren't that impressive. Looking at Trihex for Yoshi's Island, you see why 100% is more impressive and requires more skill.
