Player counts over time, as we observed them.
- Counts people running the game through Steam only. Players on other stores, consoles or launchers are not included.
- We poll the busiest games every 15 minutes and quiet ones as rarely as once a month, so a short spike between polls can be missed. Each game shows how often it is polled.
- Our player history starts on 19 October 2026. Earlier peaks, including launch peaks, are not in our data.
