A game can have been a phenomenon without ever having a big concurrent population. Mount Your Friends peaked at 1,141 CCU but sold to thousands: its moment happened on YouTube, and people played it in short bursts at parties. Ranking on concurrent peaks cannot find that game, and it is the whole point of this list.
So this ranks on audience rather than concurrency:
party_ratio = total reviews / all-time peak CCU
abandonment = total reviews / current average players
ghost_index = log10(audience) x log10(abandonment)
Gated on party_ratio >= 2.0, which cleanly splits two worlds:
| party_ratio | what it means | examples |
|---|---|---|
| 0.1 – 1.3 | a server game; the fun needed a crowd | Monaco 0.1, Cube World 0.3, Splitgate 1.3 |
| 2.5 – 17 | a party game; the fun never needed a crowd | Nidhogg 2.5, Mount Your Friends 3.8, Stick Fight 12.9, Who's Your Daddy 17.3 |
That single ratio does double duty: it identifies the cultural flash in the pan, and it guarantees the game is still playable by exactly two people, because it never depended on a population in the first place.
Also gated on: at least 200 reviews, still purchasable, carries a Steam online-multiplayer category, and not superseded by a living sequel.

(The flash-in-the-pan view, for live-service collapses instead, is analyze.py --objective flash.)
These look dead on the numbers, but the players moved rather than left. Matching requires a distinctive shared token (document frequency <= 8), a later appid, and 3x the live players — so warhammer does not link Vermintide to Total War, but vermintide does link it to Vermintide 2. Known false positive: Meadow → Cloud Meadow, unrelated games that happen to share a word.

SteamDB is the only source that ranks games by all-time concurrent peak against current players, so a browser capture of its Party Game and Local Multiplayer charts defines the candidate set. Everything else is pulled into a local SQLite mirror and queried offline: steamcharts.com for the full monthly average/peak series (SteamDB puts averages behind a login), store.steampowered.com/api/appdetails for purchasability, release date and the online-multiplayer categories, /appreviews for review counts and a keyword scan of recent reviews for dead-server reports, and api.steampowered.com/.../GetNumberOfCurrentPlayers for live counts of each game and of its sequels. 802 apps in the mirror.
Two gotchas worth writing down. Steam's appdetails success flag stays true for retired games, so purchasability has to be derived as is_free OR price_overview present — without that, six known-dead games were scored as live. And Early Access games report their 1.0 date as the release date while the playercount series starts years earlier, which produced a peak 63 months before release until the earlier of the two was used.
