First off this MOD is absolutely fantastic. I consider Civ 4 to only be Civ 3.5 then BtS to be Civ 3.8 and then this MOD makes it Civ 4.0!
However though I have a complaint about the World levels
The maps are huge which is great, but there are too many damn civs starting especially considering the Revolution Mod is on which creates even more. Not only does this slow up the game, but since there are so many Civ associated with Europe (a rather small part of the entire world) no Civ beginning in Europe (French, Spanish, Germany, etc) can become a world superpower. I think there needs to be a new map where there are only one or two starting Civs in Europe and various Revolutions will determine who will stay.
Also I would be hard pressed to find a person that owns a computer which can run this World scenerio after about 1700 AD when the world map is revealed and there about 35 Civs you have contact with. Each turn takes a long time to load and after about 4-5 turns my game crashes.
If you could make a map for the World where there are only about 12 Civ all in realistic starting locations that would be fanatastic.
Anyway keep up the good work with this MOD.
