If my start location has barbarian problems, (Spawn frequently), I'll almost always go Slinger -> Warrior -> Slinger -> Scout. Giving me 2 Warriors, 2 Slingers-Archers, and one scout. If I'm playing on a large map I'll probably go with a second scout. If I can easily defend my start location then I'll do Slinger -> Scout -> Worker. Higher difficulties the AI will declare war on you 20 or so turns in with a whole horde of enemies.
Overall I'm pretty happy with Civilization 6. The major complaints of the game come down to balance issues, and the higher in difficulty you play, the more complaints you'll have. I've often found half the AI in the game will expand 2-cities, and then no more. One issue here I think is that the move from Renaissance -> Industrial -> Modern is far too quick for the human player. Because most of the AI has some sort of bug with expanding, their science gain falters heavily and you'll quicky outpace them. They also don't use ranged units, and never use modern ones.
As soon as modders have access to the SDK, all of this issues and many more will be solved.
Civilization VI provides a much better platform to build upon than any of the previous Civilizations, but for now, I'd recommend waiting to get the game if you play above Prince difficulty. Especially @alexwhiteplays, because it often feels like you are taking advantage of the AI in a very ungratifying way. It's basically the feeling of finding out someone let you win. Oh, they weren't even trying... - that type of feeling.
But there's already quite a few mods, and I highly recommend going to www.forums.civfanatics.com - as they are the go-to place for the current non-SDK mods. (These mods are often just simple text files until the tools are out)
