How about making independent Copenhagen spawn 1 turn before Viking spawn with population 2 (lesser change that it would be razed if "Barbarian who failed to attack rome" occupies it) and flip right when Viking spawn to represent Denmark ? I don't like either went Dutch goes around there and found Frederikstad or German goes there and found Hamburg etc etc..
To make sure Viking do not expand to Dutch or German core, makes area of Kopenhagen
green (no problem on settling or conquesting city here) in Stability maps, Area of present denmark as
yellow (much stability penalty for settle or conquest) and area outside present denmarks as
red (Forbidden to settle or conquest)
What do you think ?
About pataliputra, sure it's a bad place before Calendar is founded..
Anyway, isn't its Indian job to found calendar as soon as possible so they can grow variety of spices etc so European cames from far far away to trade the spices from them ?
Alternate ending for religion problem, according to me, is making a "whatever its called" in Python so when any Civs found a tile there, they automatically have a minor religion, can't be a state religion, can't spread, and don't have holy city.
For example,
-Inca spawn and found Nazca as it's first cities. Nazca is founded as a capital and having a religion called, let's say, Andean. This Andean religion can't spread, and if Inca found the second cities where the religion still have entries in "whatever its called" in Python, say, Arequipa, there's automatically Andean religion as well. But if for example, Inca goes far far away and settle a tiles which lets say, present day Buenos Aires, there's no Andean religion there since it's do not have entry in "whatever its called" in Python.
Could that be possible ?
-Wait, I think I remember Baldyr said everything is possible if you know programming, lol-
If it is, we can have as many religion as it is, with only 7 is playable, and many minor religion which are nothing but decoration
Then we just need to map, which tiles will automatically have x Religion, which tiles have y religion, etc
