As an experiment, I've decided to adopt non-aggression as a principle when playing Civ 6. For me, this has the following implications: Don't declare any wars. Don't capture any cities. Turn off barbarians. Because they're designed to be intolerably annoying unless you wipe them out. Anyway, the distinction between barbarians and civs is a false one: in real life, 'barbarian' is just a stage that tribes go through before turning into civs. So far, the experiment seems moderately positive. I don't really enjoy the repetitive hassle of capturing cities or squelching barbarians, and I can concentrating on founding and developing cities. I don't need to bother with battering rams, catapults, etc., because I won't be using them.
