This mod needs most of all unit models and other material:
Here is a list of mods that could be added (under permision) in DoTS to complete it.

Princes,Kings and Heros.
The mod is long ago inactive but many models of English knights and many models of strat_map castles and battle map ones had been created.
Tsardoms TW.
The mod has exelent scripts,interesting strat_map models and a large qauntity of Rusichi style units and many of better quality!
Balkan Slavic factions or AOR units or Rebel factions can be created by that material plus they have interesting Ottoman units as well.
War of the West
This mods also focuses arround England but its material with a good skinner could provide exelent French and German rosters as well.
Their scotish and other rosters can offer Scotland's unit roster, Irish one plus many welsh and other AOR units.
The mod requires Rusichi animation pack though.
My knightly horses are available through that mod. They can replace all knights horses of all factions with diferent cloth textures.
Rusichi TW
The mod that created all mods after its own release.
Its horses and Russian rosters plus its wonderfull start_map and 2d art are perfect additions to any mod. Not to mention their AOR and Mongolian units as well!
Its flexible and complicated scripts can add a real Feudal era in DoTS.
The mod is free to use thanks to the MARKA team generocity !

In the future i hope that i will be still "arround" to come up with more Romans (Komneneans) too.
