I feel like there should be Difficulty Based Categories considering Hard Mode is incredibly rough, and any new speedrunners might not want to have their time beaten because of difficulty settings. Someone did an All Quests run on Hard but because of the lower stats and easier AI, Normal can make incomparable differences between times of a Normal or Hard Mode Speedrun.

This is something I've been meaning to add for some time but I've gone ahead and added Hard Difficulty for both Any% and Any% Co-op. Enjoy!
