You make an excellent point on Ooblet% when it comes to consolidation and have some great category suggestions.
I get what you are saying about a certain ooblet being a spoiler, though I don't know if I agree with you on narrowing the scope on those categories. The way I look at it is that speedrunning a game is very often something that is inherently tied to spoilers. Such as watching other people's runs to get an idea for routing can lead to seeing the ending of the game. Therefore I don't think that should limit a run category but that's just the way I see things.
I wanted to create a thread dedicated to brainstorming possible run categories, along with throwing out some ideas of my own.
The first few ideas I had revolved around a kind of completionist mentality. Ooblet% - Having at least one type of every ooblet in the game TrueOoblet% - Collecting all ooblet varieties of all ooblets in-game Collectable% - Finding all collectibles in the almanac Figure% - Complete all figure collections in town hall 100% - Complete game with at least one of every ooblet Max% - Complete game with having completed almanac, collecting one of every ooblet including all varieties, and completing all figure collections in town hall
I also had a few other random ideas such as runs for getting oobnet towers on, or getting all the high scores in Port Forward (which I feel like could be broken down into further runs based on whether bought or gotten through actual play of games).
I'm not sure how much interest might be in any of these run ideas or if they might be any good but they were just some things I thought of as possible ideas.
