was gonna recommend considering piracy, but since its against the rules I will respect that and recommend some of my favorite games i play on the SD and my PC instead:
- very chill relaxing game: https://store.steampowered.com/app/1455840/Dorfromantik/
- one of my favorite games of all time: https://store.steampowered.com/app/548430/Deep_Rock_Galactic/ (ROCK AND STONE!)
- really good online FPS (i dont actually play this one the sd as i dont like playing it with a controller but ive met people on there that do): https://store.steampowered.com/app/2073850/THE_FINALS/
- and for lasts a non steam game: Minecraft, no not bedrock edition (i dont think that even runs on linux well) java. install the prism launcher and then with that use a modpack with the controlify mod, it has built in steamdeck support. Such a cozy experience playing MC on the Steamdeck, especially with a friend that you're next to irl.
I've never been in a situation where I'd need to know how to do cpr. Yet I've learned how to do it.
