Hey I'd like to write my feedback about religion which should be further included in the final game.
First I'd like to ask you to change the name of Romuva to Vidilism, name from CK3. Romuva is modern neo-pagan movement.
Folk Christianity - Christianity as impacted by superstition as practiced by certain geographical Christian groups,
[53] and Christianity defined "in cultural terms without reference to the
theologies and
histories."
Rus and Poland christianized in the late 10th century. The spread of the religion happened exactly opposite to the Roman Empire where small christian communities eventually became the official religon. Even then it took around 3 centuries for christianity to dig in for good. While, new religion in countries which christianized themselves thanks to its neighbours/trading partners (Poland-Bohemia, Rus-Byzantium) was accepted by the upper classes first and then slowly to the folk.
It's difficult perspective because now cities are liberal, anti-religious and progressive in the modern sense. They aren't religious strongholds as in 1300s.
It wasn't for the next 100 years since official conversion of the country when lower classes begun to be christinized. In Poland especially in 1138 the
Pagan reaction occured a series of rebellions against the central authority and its most hated visible symbold the church's cross. It almost wiped Poland and central institutions in general, of the history map. Those happaned almost exactly 200 years before the start of the game,
only 3-4 generations.
The point in all of this is that it's impossible for 1337 map of central-eastern Europe to be flat-100% Catholic/Orthodox. Upper classes didn't give much of the thought about peasants and peasants didn't give a damn about what current country they were living in. In closed feudal sociaty with clear social boundries religion couldn't spread so quickly.
You my Swedish friends have already included Norse pagan religion in-game Sweden around
Uppsala old temple which fell to christians in
1080s
But you haven't yet included Slavic pagan religion, which should be all scattered throughout Slavic countries, but in one special region it should've been included for sure.
Because there is
Arkona, a temple-site of organized slavic pagan religion of the Rani slavic tribe at the island of Rugia which fell in
1068.
Temple at Uppsala has no clear archeological site while Arkona has. Uppsala is present only in written sources and its fall is roughly estimated at 1080s. Meanwhile we have exact date for Arkona, 15-16 June 1068.
But idk, 1068 vs 1080s maybe is really a huge difference.
Slavic tribes also continued to raid in viking-style Scandinavia till the 1180s. They sacked capitals of Denmark
Rosklide, Norwegian
Kanugahella (modern Kunglav).
On one funfact: Slavs won
an uprising against HRE in 983 and stopped German crusading conquest for about 200 years. Beside Baltics they were the last European pagan countries.
