Nice list Raz. Heres a bit from me;
=================================
The number of maximum units for the player to control in tactical battles is hardcoded (18)
=================================
The maximum number of land regions is hardcoded (109?)
=================================
Tha BYZANTINE faction leader gets a hardcoded bonus of +2 influence, +1 command in the early/high eras, and loses them in the late era or before that if a new emperor not of the Comnenian family line (the Angeli) takes over by civil war.
=================================
The maximum limit of land regions a land region can be connected to is hardcoded (15)
=================================
more to follow later (assuming you pay properly)...
