I haven't played them recently, but I've played CK2, CK3, EU4, Vicky 2, HOI4, Stellaris, one of their Age of Wonders games briefly (cant remember if they made or published them). EU4 is my bread and butter as I've got over a thousand hours on it, but I've put a fair amount into the rest with the exception of Stellaris. Didn't really like Age of Wonders though. Strategy games are my favorite genre although I like to jump between varying genres and not get stuck on one for long periods.
