Civilization Series, Humankind, Hearts of Iron, Europa Versailles & Total War WarHammer.
People tout these as the pinnacle of strategy based games.
I have a love hate relationship with strategy based games.
I want to play them so badly I download them, try to play them but get bored the hell out of it as the other players online take ages to complete their turn or if you are playing vs CPU you won't understand what is going. One turn a CPU player will request to form an alliance with you and the very next turn you catch it sending spies to your country so yeah no consistency.
Even before the game completes (1 complete game can easily go >6 hours), I start to hate myself for playing the game. Gets ganged up CPU near the 3 hour mark and lose badly.
Rage quit & uninstall game.
After a month or 2 once again convince myself that those are awesome games so it not the games fault but mine.
Download one them again during the weekends. Repeat
