First reading taken Aug 9, 2026 — the chart appears once there are two.

Only the games with a PC port appear here, but where Steam does report it is a real concurrent-player count rather than a proxy for one.

Not tracked for Subsurface Circular: Google Play, App Store, Discord, Reddit, YouTube, Twitch. A platform appears here once the game has a link to it — most mobile games have no Steam port or subreddit, so a gap is normal rather than a sign the game is small.
