If you are looking for more mods to spice up Crusader Kings or Attila, look no further. These mods are not needed and are subjective but we recommend these. All these mods are compatible with CW.

Crusader Kings 3
Cities of Wonders 3
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2901477267
This mod allows castles to be upgraded to new levels after they reach level 4. This deepens then campaign, making certain historical cities more influential and making conquest more important.

Medieval Arts and Medieval Arts - More Special Buildings
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2452585382 https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2692079378
Adding flavor and more special buildings, these mods work well with CoW3, further making some locations more profitable than others.

More interactive vassals
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2712590542
Depending on the settings you set in the game rules, vassals are way more interactive in war. In vanilla vassal alliances are almost useless which is highly unrealistic. With this mod, relationships with your vassals and your enemy vassals make for way better roleplay and wars.

Community Flavor Pack
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2220098919
You all know this one, its great, its compatible, use it.

Petty Inheritable Traits
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2394747105
More traits to make the perfect heir.

Advanced Court Positions
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2790056770
Ketaros created many great mods and this is one of them, adding many new court positions. Many of them have level up traits, meaning the longer someone has a position, the better they get. Note that you do need Royal Court and Northern Lords for it to work.

Total War: Attila
Medieval Warfare - Graphic
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2435164047
Changing Attilas dark colors to something more colorful, closer to CK3. Put this mod at the top of your loadorder in Attila.

Attila Ultimate Animations (Medieval Kingdoms 1212 AD version)
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2832751268
Adding more matched combat animations while keeping close to 1212AD. Again, this needs to be placed above every 1212 mod in the Attila launcher.

Anno Domini: 768
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2695905425
A great reskin for the AoC DLC. Make sure you subscribe to all needed parts and have them in the right order.

Performance Maker for massive battles
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1493472759 https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1485425742
Self-explanatory. Attila doesn't run that great, this mod helps. One version works without the Blood and Burning DLC, the other is for people who own it.
