Giving Civ6 one more try so I've got a beginner question here. How far apart do you build your cities? I like to place them pretty far apart so that each city will have lots of tiles to work. And they'll cover more territory. But I see lots of vids where people will put their cities close together so their Civ is sort of 'packed in'. What's your strategy for placing cities closer or farther apart from your other cities?
