A sub-10-hour 100% TOTK run would require maintaining the following average times, simultaneously:

• Collecting one Sage's Will every thirty minutes

• Obtaining one Pony Point every fifteen minutes

• Collecting one Autobuild schematic every thirteen minutes

• Collecting one Paraglider fabric every twelve minutes

• Completing one side adventure every ten minutes

• Activating one Lightroot every five minutes

• Completing one side quest every four minutes and 15 seconds

• Collecting one Bubbul Gem every four minutes and six seconds

• Completing one shrine every four minutes

• Defeating one yet-to-be-defeated miniboss every two minutes and 13 seconds

• Completing one Compendium entry every 70 seconds

• Collecting one Korok seed every 36 seconds

• Collecting one other miscellaneous map objective (named locations, caves, etc.) every 29 seconds

Overall, there are ~3,700 objectives necessary for 100% completion: you would need to be completing at least one objective every ten seconds on average to not fall behind.

That's assuming all three hours of cutscenes are skippable - I never tried to skip any, so I don't know if they are; it also doesn't include a few other things, like obtaining & upgrading all permanent/non-sellable armor, fully upgrading the Purah Pad, finding all Bargainer Statures, finding all Old Maps, etc...

I think this may genuinely be physically impossible.

@evergreenemily It blows my mind how much stuff there is in this game. Now I understand why it took seven years. I haven't even found some of the things you mentioned yet.

@ForrestTaylor Absolutely worth the wait. It's wild how huge this game is.

I'm 180 hours in, and I've found/completed...65% of the Sage's Wills, about 75% of the Pony Points (before max reward), about half of the schematics, like 30-40% of the Paraglider fabrics, about 75% of the side adventures, all of the Lightroots, like 25-30% of the side quests, about half of the Bubbul Gems, all of the shrines, like 25% of the minibosses, the full compendium (mostly because you can buy pictures), and roughly a quarter of the Korok seeds. I might put more time into TOTK than I did into both of my BOTW files combined (~300 hours) and not even break 90%.

@evergreenemily Yeah, this was a poor over-under, especially once the details of the game were known

25 hour version: https://manifold.markets/JimHays/will-anyone-submit-a-100-speedrun-o-baa33947a964

A commercial showed that Korok seeds are returning. If there are 900 again, you would need to collect 1.5 per minute to complete the game in ten hours - assuming you spent zero minutes doing anything else.

@evergreenemily Update: I dunno how many there are, but I've been finding several all over the tutorial island. I don't think it's physically possible to 100% this game in less than 15-20 hours.

There's gotta be a Korok seed equivalent in TotK.

@ForrestTaylor Seems likely, but will it be more or less extensive?
