That, as others have mentioned, is a moderately difficult question for us without knowing what you like or what the specs on your laptop are.

If you install Steam, they have a pretty generous return policy. You just need to act within 2 weeks of the purchase OR before you hit a total of two hours played in that game - whichever comes first. I like Steam because the Proton compatibility layer built in makes gaming on Linux so incredibly easy.

I'm hesitant to do so because you undoubtedly like different things, but here is a short list of some of the games I've played that I really enjoyed based on total time played.

Sid Meier's Civilization (the whole series is good, but 5 is my favorite)
Stellaris
Battletech
Satisfactory
Valheim
Football Manager (think of this title as the complex strategy game to FIFA's action game)
