Kodansha

Figures across every listed Steam game a company developed or published: the people playing them now, the share of their Steam reviews that recommend them, the games released each year, and their reviews and players month by month.

• Steam has no company IDs, so two different companies with the same name share a page, and a company that changed its name is split across two.
• Monthly players before October 2026 cover only the most played games, the ones the archive holds, so a company of small games can show players only from October 2026.
• Players now adds up readings taken at different times: busy games every 15 minutes, quiet ones every few hours or less often.
• Delisted games, soundtracks, DLC and tools are left out.
• Counts people running the game through Steam only. Players on other stores, consoles or launchers are not included.
