Religion:
OOoh! Here is an idea, just an idea mind you, but it sound like it could be... neato.
Make religion a point based system, like Crime/Fire/ect, where the more religion you have in a city, the more religious buildings you can have in the city. Say, you get 1 point per turn per religion in the city, and say 1 per priest and 2 per GP in the city. At each 100, you can build 1 (ONE) religious building in the city. Each subsequent 100 you can build a new one. So if you have all 2,000 religions in the city you can't just build every religious building and get a huge tech bonus from having 2,000 monasteries. Say, once you hit 500 you can build a bigger version of one of your religion's buildings. ect ect.
*rubs chin* Hmmmmm

It took awhile, heh... But back on subject. Back when my civics were a modmod, I found another mod that made it possible for techs to give +
+
%s. I wanted to remove Language then, but Hydro reminded me that we still meet them to provide the minus diplomacy in early eras. I'm sure if we found a way around this, it'd be alright with him if we removed the Language category. Also, I know no one is working on this, but I thought I'd like to bring this issue up again from T-Bird:

, +1
(Base)
(Caste)
(Feudal)
, +1
(Mind Control)
