Not sure how many there will be, but I figured having a thread is not a bad idea 
For now there is only one (which might eventually be broken down into components)
World Sizes
Adds two new world sizes to Civ 5 (XXL at about 1.5 times the size of Huge and Giant at about 1.5 times the size of XXL). The new sizes are only available via the drop down list in the advanced setup (I do not know how to change the UI to do so yet).
To keep the ratio betweens civilizations and minor civs (1:2), the mod also adds some new minor civs.
All texts in english only.
