The correct Steam game record
Halloween: The Game uses Steam App ID 3219630. The official store record and SteamDB chart page agree on that identity, which prevents similarly named games from being mixed into the data. App ID is stable. Current players, 24-hour peaks, historical peaks, review totals, and store ranking are dynamic values.
Why no live number is shown here
The Steam interface call used during material collection did not return a usable current-player number. That result means the figure was unavailable in that request; it does not mean the game had zero players. SteamDB can display current and peak figures, but those values are a changing third-party snapshot. A static guide should show them only with a precise capture time and a fresh read.
Reviews are not player count
Steam review totals and positive percentages describe submitted user reviews. They cannot be substituted for concurrent players, owners, sales, or active users. Not yet confirmed in the collected evidence: a reliable live concurrent-player count at publication time. Use the linked chart source for a current reading and note when it was checked.
