Steam Charts
A public reference that records hourly Steam concurrency and presents recent peaks, monthly averages, and historical trends.
Why use it
It helps assess multiplayer activity cycles, event impact, and long-tail health while choosing competitor observation windows.
Where it fits
Study the market and the players you want to reach, then turn a loose idea into something you can test.
What to check
Concurrency is not sales, retention, or profit; Steam API and collection changes can create gaps, and peaks are especially incomplete for single-player games.
