My most played game was Brotato. It just plays so well and one run lasts about 20mins which is perfect for me when I don’t want to commit too much time.

My most surprising game is probably a Trackmania which took a while to get working because of the Ubisoft launcher not playing nice with Linux but then again there are so many guides to get it working it’s not that big of a deal. For me I had to change the wlan MTU packet from 1500 to under 1000 and all was well.

Outside tinkering I’d suggest Heaven’s Vault. Adventure/Puzzle game where you decipher an unknown language from glyphs. You can quit and next time you pick the game it will give a summary where you left last time storywise - such an awesome quality of life for short gaming bursts
