How this guesstimate is made
Cost to make. Modeled as 25–90 people over 2.5–5.5 years at a loaded $105k–$175k USD per person-year. Development only, not marketing. Not a published budget.
Steam earnings. Steam earnings in USD from ~1.5M–3.8M copies × a mix of US list and sale price.
Development time guesstimate: 2.5–5.5 years. Confidence: medium. Time uses studio scale or a published figure. Cost to make is headcount × production years × a loaded USD cost per person-year, or a filing/interview number when one is on file. Steam earnings (USD) are reviews × a copies-per-review band × a mix of US list and sale price. These are independent algorithmic estimates from public data — not factual, not publisher books, not Valve.
