How this list is built

Games are ranked by Steam review count, the most reliable public proxy for sales when actual figures are private. Each title links to its indielist page, where the white-box sales estimate expands into the full Boxleiter formula, so you can audit the number rather than trust a black box. Review counts come from Steam; sales figures are estimates, not official sales data.
