There may be more that work but as I said I spent a few hours getting the Error 30...... message and these 3 were the only ones I got to work with it.
Some Tips
when Creating a game go to advanced create game and select rule set Westros and Essos.
Amenities will be an issues for resources are spares in the game. so when founding a religion make sure you choose Stupas for the extra Amenities.
If playing Dothraki or Targaryenn don't spam out too many settlers 8-9 founded cities is plenty conquer all the rest. All other civs there is not enough room to spam settlers anyway. This is because of Amenities.
If playing Targaryen and of cause you will because dragons are awesome remember they cost 50 per turn in maintenance so watch your Gold per turn.
Not sure if this Mod will work but might come in handy if it does. Removable Districts RaF (or the Vinilla Version if you can find it)-

I hope this works for you have fun
