Another request I would really like to see, was a mod where each Civ kept their Pantheon. It doesn't make sense that a historical Pantheon should be wiped out. Danmark and Greece are Christian Nations, but they retain their respective pantheons IRL, Norse Mythology and the Greek Pantheon. And the Egyptians, their Pyramids are culture today, reminiscent of a faith and worship they long abandoned. Ancient Pantheons are part of who we are today.
In game, it is so annoying that you must choose Pantheon for a race at religion. If you want culture from pastures, or hammers from fishing boats, then at higher levels you might very well miss religion, and thus lose a Pantheon that probably was essential for making that particular map fun.
