This is my, can't live without, mod. It is the way Civilization should be played in my opinion. However I do have a few suggestions:
For some reason I can't see the espionage icon on my screen, its just blank.
New civs (Papal states (my favourite civ), Argentina, ect)
Plagues (like in Rhyes)
Some of the future techs from Future War (would be awesome to have clones)
