I’m still waiting on some of the total conversions to get more developed, so I tend to stick to QoL mods. Here are some of mine:
In My Humble Opinion adds the ability to see what your current character links of a character you’re looking at - just like in CK2 which is great for some quick RP
Prisoner’s of War is a great small additional in which characters taken captive in battle don’t just teleport to the war leaders dungeon and are instead held by the capturing army until the make it back to their borders.
What are your favorites???
New religions and culture, as well as clothing, units, characters and art. There are also some region-specific events that can pop up.
It does suffer from the same problem as all of ck3, which is that it isn’t different enough from Europe.
