Better Assimilation and Conversion
PLEASE LET ME KNOW IF THE ASSIMILATION IS QUICK ENOUGH in plains provinces. Also, do not expect it to be very quick before the culture war kicks in, so pre 1500 or so.
Changes cultural assimilation and conversion in three ways:
1. Makes it so that a country can only assimilate if its main culture is 25% of the population. This is to stop a fully Baltic German Dorpat, a fully Mongolian Golden Horde, a fully Venetian Cyprus, a fully Catalan Athens etc. by 1350. This probably breaks some countries, so let me know in the comments. Culture war / time should make up for it though.
2. Terrain affects assimilation and conversion, with harsh topography and vegetation making assimilation very difficult.
3. Makes non-primary culture pops grow in cores. Yes, apparently all new pop growth in your cores would be only your primary culture, which is insane.
