a couple of more complicated ideas I'd like to add some time soon: 1. remote resources. I want civs to be able to access far away resources without building cities on them, like colonies in civ III. this would be mainly so that one of carthages UHVs could be getting amber and furs from n europe via the sea, but it would also enable putting spices on 1 tile islands and getting the copper from cyprus. it could work this way: put an invisible route on the map following all the coasts and use an improvement that generates 1 culture when built. 2. food trade routes like civ II. someone did it here: http://forums.civfanatics.com/showthread.php?t=333270. this would mean the romans could have a "make rome the biggest city" goal requiring them to import egypt's food. 3. the great synthesis: this the mod's religious victory, but instead of having different victories for different religions, there's just one and the more religions you have, the better. it will be based on the united nations and require something like syncretism, 3 shrines, 2 academies and 5 cathedrals. so to win you will have to build the great synthesis and then convince enough other civs that you have indeed brought the world's great faiths together.
