Even though this would be a long stream, there should be a new category where you start from a new game and complete all challenges, or call this category 100%. They just complete all challenges as fast as possible in any order, unlock all characters and stages. The only thing that should be banned is playing vs over and over to get characters. DLC should be decided by you guys if they should be downloaded or not

Why combine multiple categories into one when they already exists with multiple runs separately. A "New Game" category for this game wouldn't make much sense because there isn't a set story mode, as well as multiple separate game types to do. (Classic, All-Star, Multi-Man, etc.) To combine them all into one category wouldn't really be effective when you could do all of them separately, at least the ones that exists. Also, 100% category would consider ALL trophies, which would be way too long of a run. Super Smash Bros. for Wii U features 716 trophies in the vanilla game and 743 trophies with DLC.

Doing all challenges does seem a little arbitrary but im not one to say you cant speedrun something, if you show me a route and a completed run of the category i will add the category to the leaderboards @drayden15

Well if people do some runs of the category or really work on it I'll make the category no problem!
