Individual prerelease counts require verified game access. GaugeDB can record a count if Steam publishes one in its public chart, or when collection becomes available after release.
No Steam player count has been recorded for Undersea Post Office Sim yet.
Concurrent Steam players, not daily or monthly active users. Console and other launchers are excluded. Peaks cover GaugeDB’s recorded history.
Run the last post office on the seabed. Weigh every parcel, price it to the exact stamp, catch the forgeries, and pack the day's mail into a fish-shaped cargo hold that has to hang level. Four weeks. Four rent days. One desk between you and eviction.
