Steam collection.
Build a research catalog from a release period. Control downloading in the collector application.
Collector application
ClosedOpen MMM.Collector.exe or Start-Collector.cmd to collect games. Its visible window shows progress. Close that window whenever you want to stop; reopening it continues saved work.
Automatic collection and scheduled observation refresh wait until the collector application is open. MMM remains available here.
The window status updates when you refresh this page. After closing the collector, it may take up to 25 seconds to show Closed.
Collection activity now
Snapshot: 06 Nov 2026 18:51 UTCCollector closed
No collection is currently marked Running. Paused collections require Resume; completed collections have no remaining work.
Rolling hour: after 06 Nov 2026 17:51 UTC through 06 Nov 2026 18:51 UTC. These catalog-wide figures count newly added Steam releases, including manual imports; they do not count games released during this hour or observation refreshes.
An unchanged catalog count is normal when a daily pass finds games already tracked, and after a collection completes. Use Refresh status to load a new snapshot; no automatic refresh is enabled.
Automatic new releases
EnabledEvery day at 03:00 Europe/London, collect releases from the last seven calendar days, including the day of the scan. Existing games are kept without duplicate imports.
The next pass is due. It will start automatically when the previous daily collection has finished.
The collector application must be open. After downtime, one catch-up pass scans the latest seven days. Daily passes take priority over manual collection and share its request limits. Disabling the schedule leaves any current pass running; use its Pause button to stop it.
Release period
The dates are inclusive. Paid, free and VR games are eligible, regardless of review count. Existing catalog games are kept; their regular observation refresh continues separately.
Coverage and interpretation
The source is the US Steam store search, ordered by release date. Collection reads successive pages until reaching releases older than your period or the end of the available results. Store details confirm each new game's release date before import.
Store search can change during a pass and may omit unavailable or region-restricted titles. A finished pass does not guarantee complete Steam coverage. Repeating an overlapping period can catch entries added or moved later.
Skipped entries include releases outside the period, upcoming games, unrecognised release dates, unavailable entries and non-game products. No empty observations are created when Steam fails.
