In my experience, action games on a small handheld are inferior to playing on a desktop or big screen with controller. The Steam Deck is heavy and gives you far less dexterity than when playing with a console controller, and the extra energy spent holding the device detracts from ease of playing high action games as well.
So I’ve mostly given up on playing fast-paced and action games like Doom or Hades on Steam Deck, preferring to play those on my Desktop or from the couch with a console controller. Instead I’ve found turn-based and slower paced games like Darkest Dungeon and Stardew Valley to be much more conducive to the Deck.
Here’s some of my recommendations, but I’m very much looking for others, so please let me know your list:
- Darkest Dungeon
- Graveyard Keeper
- Stardew Valley
- Coromon
- Monster Train
- Pillars of Eternity
- Disco Elysium
- Into the Breach
This might not count? But, in terms of slower paced - the slowest I play on Steamdeck is Skyrim.
Technically an action game but the combat is easy and not very reliant on reaction speed. Most of your time is just exploration and questing
