I really like this idea too, altogether. How would you earn these RPs though? Through culture? That would mean that to achieve a cultural victory, you could never touch religion. I also worry that it might just become a sort of copycat SP. If it was done well, it would be great, if done badly, it would be a waste. I like the idea of those specific religious buildings. I agree it would be a great idea to go beyond the simple wonders founded by great people in civ 5. However, if we were to do this, it would have to be for made up religions or just for religions that nobody believes in any more. If you make Christianity and Islam have different traits, there is a chance that people could be offended if they believe one to be better than the other. You can just imagine the idiotic threads now with people saying that firaxis are 'commie b*****ds that are making muslimism look better' or someone complaining that firaxis are biased towards Christianity due to their 'blind american patriotism'. I'd really like to have certain religious buildings like you suggested to help identify certain civs and to enhance certain things. All in all, I think your ideas are great.
