Don't really know if this could become it's own category per say but it could be a fun challenge nonetheless ^^ ... kinda like the bingo challenge in other games, but using one of the game's feature. I'm interested in trying it, it can be fun ^^ ... But the rules are kinda flimsy right now... and I think it need a bit more thoughts before people could really engage in this sort of challenge ^^

First question : Do we have access to items at the begining of the challenge ? Just tools ? Which tools ? Wouldn't it be more fun to have to find and craft the items we need to complete the challehge ? If the answer to the last question is yes, can we use our workbench or do we need to use Tom Nook's ?

Second question : Is the player allow to setup the island beforehand ? Planting flowers only around the player's house, planting trees nearby, putting its house near the water can be viable strategy to allow a quicker completion of some of the tasks. What about putting items on the floor in advance ? Is that allowed ? Is using the shop okay ?... Speaking of which, at what point of the island development should we be ? Because if we play on a island without the shop, for example, we can't have a task about spending or gaining bells... which can be seen as a thoughest task than catching five bugs. Speaking of bells, do we have bells at the start of the challenge ?...

I think it's the biggest roadblock in the idea of this challenge becoming a run category : things can be done before the real beginning of the run. Things can be set up. And nothing can prove that the player hasn't look at the tasks before begining the recording, thus letting him plan his path.

So... yeah... I have some reservations about all of this. But at the same time, it sounds kind of fun and I want to try it ^^ ... But the challenge must have some ground rules first. And even with them, I don't really know if it would work as a run ^^

@_Brendan : As far as I could see, the task "Catch some type of fish" always seems to concern a fish catchable on the island at the time of the task (month and hour of the day).
