The way they warp how you play should be insane. Weird part to me is that you'll probably not want to hammer out much of anything except districts and the occasional wall. Going to have to revisit the conversion into yields on projects and basically taking a fairly different approach to trade routes and policy cards is also fun.
Wonder if that 50% settler buyout thing will still be a big thing. This is a Civ I feel will start slow and isolationist and can quickly explode in the mid game.
Don't forget, Mali can also be a Faith/Religion powerhouse from deserts, and Faith is another form of Gold/Production: get Monumentality in a GA and with Mali's Faith production, you will never have to build or buy with Gold another Builder or Settler until the next Era: you can spit them out with Faith points and surge in size. I confess if I get a strong faith start for whatever reason, I use the Faith not to spread a religion (I detest the Religion Game) but to 'hoard' Faith Points to 'buy' Great People, Settlers and Builders. As soon as I get a Golden Age, and I can usually manage one no later than the Medieval/Renaissance Era, I have Settlers trotting out in all directions.
Mali will be able to play that game with either Religion or Gold: look for a Mali that survives the Ancient Era to be a Holy or Financial Terror: expanding like crazy in the next two Eras...
