Game calculators that answer the actual question
Not wikis, not tier lists — calculators. Type in what you want to build, or what tags you rolled, and get the exact number back: how many machines, what materials, which operators. Everything runs in your browser, nothing to install, no account.
Factorio
LiveProduction chain calculator — pick any item and rate, get machine counts, every intermediate and the raw materials behind it.
Open calculator →Arknights

Persona 5
Coming soonFusion calculator — what two personas make, and the cheapest recipe to get there.
What these calculators do
Every game has numbers that the game itself will not do for you. Factorio tells you a recipe takes 6 seconds, but not how many assembling machines that means for 60 advanced circuits a minute, or how much copper ore the whole chain eats. Arknights gives you five recruitment tags and no way to know which operators they can actually produce. Persona 5 lets you fuse anything, but not which combination gets you a specific persona at the lowest level.
These are the gaps these tools fill. Each one takes the input you already know — a target rate, a tag set, a persona — and walks the underlying data to give you the output you were about to work out on paper.
Where the numbers come from
Every calculator here is generated from the game's own data — recipe prototypes, recruitment tables, fusion charts — not typed in by hand. That matters more than it sounds: when we first hand-entered a subset of Factorio recipes, two out of twenty-one were wrong. A calculator that is off by 10% is worse than no calculator, because you build the factory before you find out.
When a game updates, the data is regenerated and the tests re-run, so the numbers on the page are the numbers currently in the game.
What is coming next
The plan is one calculator per game, grouped by genre — crafting and production games in one place, gacha and party builders in another. If a calculator is listed above as coming soon, the data work is in progress rather than the page being a placeholder for something vague.
