I’m playing two games at the moment:

Yet another run in Nier: Automata, second playthrough, first time on steam deck. It runs surprisingly well.

Stardew valley. For steam deck it’s a killer game - 8-9 hours on a battery, perfect for resting.

I also have Snowrunner and Vampire Survivors as my go to games.

Just finished Dungeons of Dreadlock. I do not like puzzle games in most cases (not my genre), but enjoyed this one.

Quite a nice game to spend 5 hours with. Cost peanuts. Was perfect on steam deck.
