Circana's weekly Player Engagement Tracker measures weekly active users across PlayStation 5, Xbox Series X|S, and Steam to rank the top 15 titles in the United States. For the week ending December 20, Fortnite remained No. 1 on both PlayStation and Xbox, while Arc Raiders led Steam's chart. The top tier held steady versus the prior week, with no changes at the very top of the overall rankings.
Among the notable moves, Clair Obscur: Expedition 33 returned to Steam's top 15, landing at No. 13 — up from No. 20 the week prior. On the console front, CO:E33 rose to No. 39 on US Xbox (up from 60) and to No. 53 on US PlayStation (up from 68).
These figures come from Circana's Player Engagement Tracker, which reports weekly active users rather than concurrent peaks. The dataset aggregates activity across PS5, Xbox Series X|S, and Steam, providing a snapshot of which titles are driving engagement on each platform during the week in question.
Taken together, the data highlights ongoing cross-platform engagement patterns for a week in late December. Fortnite's stable dominance on consoles continues to anchor the overall rankings, while Arc Raiders' Steam performance underscores the platform's capacity to elevate a title within the weekly mix. Clair Obscur: Expedition 33's rebound—entering Steam's top 15 and rising on both major consoles—illustrates how updates or renewed interest can shift position across ecosystems.
Publishers and platform holders rely on these weekly tallies to gauge market momentum, allocate marketing resources, and assess the effectiveness of releases across ecosystems. While the numbers reflect weekly activity rather than momentary peaks, they offer a consistent, cross-platform view of how engagement fluctuates across the broader US gaming market.
