For me, I've really taken a liking to Phoenicia, which I didn't really expect. I like that get some additional trade routes, and I kinda like naval powers. The ability that gives full loyalty when settling on coast on your continent can make for some fun (and trollish!) gameplay. The Cothon is a nice district. Moving the capital takes a really long time but it's a fun ability to use. My least favorite has probably been Canada (though obviously more time is needed to test out a lot of these civs). I find the lack of surprise wars to be a good ability but it also removes tension and I think Civ VI really needs that. What are your favs and least favs?
