@YuiHirasawa @ChristiJunior @LukeAlmighty @coolboymew itd be easier to list games that DONT work well on steam deck. any action game will work, FPS games mixed results depending on how good you are at controller aiming (try using gyro). some of my favorites:
katamari, the first two games have great ports that run at 60fps
shotgun king, its a mouse game but turn based so using the trackpad is comfortable
death stranding, not a whole lot of aiming and runs surprisingly well, albeit lots of text and menus
slay the spire, dicey dungeons, work great in controller and short sittings
project diva, always been a portable series but the heavier steam deck makes it a little more exhausting
monster hunter rise, not much to say just good shit
