I think it would be nice for civilizations to have unique techs, buildings and wonders. Having certain techs that they can't share with anyone else would lead to them being able to branch out and develop in different ways. Some advantages I've thought of are as follows:
1. It would get round the "how can we introduce a third world country" problem - make it so that they can never have certain key buildings/techs that make science rate speed up for example.
2. It would make civilizations even more unique and the choice a little harder - what if only the Eygptains could build the Pyramids, or seafaring civs were the only ones who could build the Lighthouse. What would you choose if only religious civs could build religious-type wonders and scientific civs were the only ones able to build the Great Library?
3. Corruption/waste management techs and improvements could vary between civs, making this another factor in your "which civ shall I play?" decision.
What do people think?
