In Civ III civilizations which shared the same cultural background tended to be closer friends (relationships between the japanese and chinese got a boost, ditto with british-french relationships). I want this feature re-implemented into Civ IV because it just seems like a very sensible addition, and would add more realism. I play almost exclusively as Arabia (Spi, Pro) because I have a soul-deep admiration for their mysterious, religious, and martial culture (I love their mystical-sounding theme music so much as well
) and I love founding an early religion. I admit that everytime I'd found an Ottoman AI I'd longed for closer relations due to shared culture, mostly because I just love their similar (both Arabic) cultural backgrounds. Does anyone else think this might be a good thing to add?
N.B. It could also be made a toggleable feature as well, so players have the choice of turning it either on or off.
