No one really competes for any other difficulties. Hardest is the most challenging, Easiest has some really quick levels, I don't think there's any case where one of the medium difficulties is the fastest.

i think adding moderate would be cool. the inbetweens dont need a run. Also the rules could be made more clear.. shouldnt it mention cheats are not allowed ? and it seems glitches are allowed ?

EDIT: realize this is a dead post but i just found this page and plan on getting my name on these leaderboards :) maybe lower a couple of these records, we'll see.

Imo even the easiest category could be removed - almost all times are worse than hardest category and not because they are more difficult, but because runners lack interest in running them. And I don't blame them. I only consider hardest category to be noteworthy, with the exception of "I'll Be Back" where the easiest difficulty is unique. (I might forget some other, but these are few regardless)

That said, I don't really see a point to include the moderate difficulty, unless there are clearly distinct optimal strategies w.r.t. hardest and easiest

But welcome aboard, I'm looking forwards to seeing some action here again! 😄

OK I added a quick "no cheats" clause to the game rules, though unspoken speedrun common sense dictates that by default, cheat codes added by developers are disallowed whereas glitches are allowed.

We used to actually have categories for all the difficulties, but nobody cared about Easy/Moderate/Hard; Easiest was kept on the off-chance of there being some interesting strategies unique to it, though overall it is kind of ignored, yeah. Could be removed at some point but I don't think it's a big deal either way.
