“Most played” depends on your ruler: peak concurrent players, sustained population, or total accumulated hours each crown different games. Here's the landscape by each measure.
By concurrent players
PUBG: Battlegrounds set the all-time concurrency record (~3.2 million players in early 2018). Counter-Strike 2 has since held the throne for consistency, routinely topping 1.5 million concurrents and breaking records repeatedly since 2023. Black Myth: Wukong claimed the single-player concurrency record (~2.4 million) in 2024, and meme phenomena like Banana briefly posted absurd numbers in 2024.
By total accumulated hours
Lifetime hours favor old, deep, free-to-play ecosystems: Dota 2, Counter-Strike and Team Fortress 2 have been absorbing player-hours since the early 2010s. Long-session games (Dota's 40-minute matches, Rust's wipe cycles) compound faster than pick-up-and-play titles ever can.

Frequently asked questions
What game has the highest peak players ever on Steam?
PUBG's ~3.2 million concurrent record stood for years; CS2 has since posted comparable peaks and holds the sustained-population crown.
What's the most played single-player game?
By launch concurrency, Black Myth: Wukong's ~2.4 million in 2024 stands as the record among primarily single-player titles.
Does “concurrent players” mean sales?
No — it's instantaneous simultaneous users. Lifetime sales run far higher for most hits, and free-to-play games blur the comparison entirely.
