My thought is that this is literally just the current any% NCD, with a couple of extra duels like Villager 1/2/3.

In other words, why.

I guess you have a point. Was trying to delete the thread for I felt a bit silly ._.

This is a common misconception with a lot of people who just don't have much speedrunning experience; the established categories are there for a reason, and just because you can think of a specific goal doesn't mean that it will be a category. Arbitrary categories especially are very often looked down upon, but in this case the proposed category is just a bit pointless because it doesn't offer anything different from what's already there in the route, other than adding a couple of fights.

For something to be considered a new category, it preferably must add something different to how the run fundamentally plays out. For this game, you're kind of stuck for what that may be. Only thing I can really think of that would be interesting, albeit EXTREMELY stupid to actually do would be a No Deck Edit run. It is technically possible to complete the game with the starting deck assuming it's good enough (THTD material + Umi + Equip giving 3800 ATK monster) and then proceed to get Easy Modes in every duel. It would never happen in a run though, which is why I'm sure nobody has bothered to attempt this.

I think I know why I was thinking that though. I, so far, have ran the New Game + and still looking up the other categories before I run them. In that run, you skip the entire beginning part. But yeah, thanks for explaining things. I've only been speedrunning in general for like a week...haha
