99 Nights in the Forest
Roblox survival game where you hold out for up to 99 days around a campfire. There is no trading economy here, so these pages do the arithmetic instead: what classes cost, what the bench needs, how long a run lasts.
Upgrading the crafting bench from tier 1 to 5 takes 100 wood, 81 scrap, 2 Cultist Gems and 1 Gem of the Forest. Reaching day 99 takes 7 h 25 min 30 s at 1x and 49 min 30 s at the maximum 9x day multiplier.

Questions
Where do these numbers come from?
From four pages of the community wiki (Classes, Crafting, Days, Diamonds), read at a fixed revision that is linked at the bottom of every page. We turn the tables into totals and calculators; the wiki is the only source and nothing is measured in game.
What if the game changed after your data date?
New classes and price changes show up here only after the wiki records them and we re-read it. The "Data checked" date on each page tells you how fresh the numbers are; when it looks old, trust the in-game shop first.
