Hard to say without some indication of what sort of thing you’d like. Are you looking for something to just power trip and blow off steam, are you looking for strategy games that make you think, narrative experiences, dexterity/reaction time challenges etc etc etc? But knowing absolutely nothing here’s 3 good games:
Stardew Valley has native Linux support. It’s a game about farming. There’s not really any consequences for doing things slowly so take your time and enjoy the game.
factorio is a strategy game essentially about optimizing supply lines. Programmer types tend to find it extremely addicting.
Baulder’s gate 3 is a Turn based RPG based on Dungeon’s and Dragons. It may be a little difficult for beginners especially if you haven’t played DnD but it is also one of the best games to have come out recently having swept all the award shows for both it’s great story telling and run mechanics.
If there’s anyone in your life who really likes gaming asking them for games you can play together or that they can watch/guide you through would be a great idea.
