Well one screenshot of my progress - as you'll see World Church and some city state allies is really making life a lot easier. I'm not really sure what Victory I'm aiming for. It was originally diplomatic but it seems like I'm picking up a heap of Wonders.
Spoiler :
From that earlier screenshot I paid Assyria to attack Greece and they eventually got wiped out completely so after hitting their capital with a Great Prophet their religion is gone which means I've completely converted Assyria and i'm working on Morocco now
