Top trending games on Steam: August 21, 2026

Counter-Strike 2 is Steam's #1 most-played game on August 21, 2026, the same rank as August 20. Dota 2 and PUBG: BATTLEGROUNDS hold 2 and 3. The board's unusual occupiers remain Bongo Cat at #4 and TBH: Task Bar Hero at #7, two taskbar idle games sitting above Rust. Trends MCP stored 10 games at 08:01 UTC. The only order change versus yesterday: FiveM climbs from #10 to #9 as Rust slips from #9 to #10.

The August 21 Steam cut is three Valve-era shooters, two idle clients and a GTA mod platform. These 10 ranks come from the Trends MCP snapshot.

Counter-Strike 2: Valve's competitive shooter holds #1. Trends MCP get_growth on steam could not complete a 7-day window (collapsed_range). The 30-day point compared July 1 (value 76.3, peak players 1,420,896) with June 1 (82.0, 1,573,727), a -6.95% value change.
Dota 2: Valve's MOBA holds #2. The same 30-day steam window put Dota 2 at value 75.1 versus 63.0 (+19.21%) with peak players 860,019 on July 1 versus 862,639 on June 1.
PUBG: BATTLEGROUNDS: Krafton's battle royale holds #3. Growth on steam for 30 days: value 19.8 versus 19.1 (+3.66%), peak 792,142 versus 820,499. See the Steam most played API.
Bongo Cat: Irox Games' keypress idle client, launched March 5, 2025, holds #4. Kotaku noted an all-time peak above 190,000 concurrent players. No August 21 patch was required to keep the slot.
Palworld: Pocketpair's creature-survival game holds #5. Unchanged; no widely reported August 21 update identified.
Apex Legends™: Respawn's free-to-play shooter holds #6. Unchanged.
TBH: Task Bar Hero: Nugem and Tesseract's taskbar idle RPG, launched May 27, 2026, holds #7. GameRant said it peaked at 104,957 concurrent players inside 72 hours, then reviews fell to Mixed over performance and data-collection complaints. A Plaguelands update is dated toward September 2026.
Wallpaper Engine: The wallpaper utility holds #8. Unchanged; it is a desktop tool, not a match-based game.
FiveM: The GTA V multiplayer platform climbs one rank. That move lines up with a week of GTA 6 leak traffic on Google and Reddit, even though FiveM is a GTA V client, not GTA 6.
Rust: Facepunch's survival game slips one rank to #10. No August 21 wipe news was attached in the fetch.

What today's Steam trends reveal

Valve still owns the podium, but idle software owns the conversation. CS2, Dota 2 and PUBG are the expected 1-3. Bongo Cat at #4 and TBH at #7 are desktop toys with six-figure concurrent peaks, which is why this chart no longer reads as a shooter-only list.

FiveM's one-rank bump is the only GTA-adjacent move on a day when Cyberleek leaks sit at Google #7. Rust giving up #9 is a one-slot shuffle, not a genre rotation. The 7-day steam growth calls failed; only June-to-July monthly points landed.
