September has officially ended today, which means we can now see which games were the most played on the Steam Deck throughout the last month. There are some obvious ones here, like Hollow Knight Silksong shooting right to the top, but I was surprised to see the newly-released Megabonk there as well. So, here are the top 20 most-played games on Steam Deck throughout September 2025:

Top 20 Most Played Steam Deck Games of September 2025
September 2nd - October 1st

New Games Added:

  • Hollow Knight Silksong
  • Megabonk
  • Deep Rock Galactic: Survivor

Games That Left:

  • The Witcher 3: Wild Hunt
  • Fallout 4
  • The Elder Scrolls V: Skyrim Special Edition

While the list didn't have many new games added to it, there are still some very prominent ones. Hollow Knight and Silksong are dominating the charts right now, which makes sense since Silksong released early last month. However, Megabonk is a brand-new game, and I was surprised to see it so high up already. Hades 2 shot up the charts due to the 1.0 release, and I still find it crazy to see Vampire Survivors so low after watching it stick to the high spots for the longest time.
