Online Co-Op is a standout opportunity for Steam developers: 18.9% of releases reach a meaningful audience (about 3.1× the 6.0% Steam-wide average), across 1,004 games tracked since 2024.
| Year | Releases | Reached audience | Success rate |
|---|---|---|---|
| 2024 | 304 | 74 | 24.3% |
| 2025 | 425 | 82 | 19.3% |
| 2026 · in progress | 275 | 34 | 12.4% |
2026 is still in progress — it covers only part of the year, and recent releases haven't had time to reach the review threshold yet, so its release count and success rate both read artificially low. Across complete years (2024–2025) the settled rate is 21.4%.
Out of every 100 Online Co-Op games released on Steam, roughly 19 break out to a meaningful audience — compared with about 6 in 100 across Steam as a whole. Online Co-Op ranks #87 of 466 tags by release volume, and #4 by success rate among well-populated genres, which makes it relatively underserved. Across complete years (2024–2025), Online Co-Op's success rate settles at 21.4% — the in-progress 2026 reads lower only because its games are still new.
Unlike "top sellers" lists that only count winners, this is an honest base rate — every tracked Online Co-Op release is in the denominator, including the many that never found an audience. That's the number that actually tells you your odds going in.
