My personal House Rules:

Objective: Play each faction as historically accurate as possible, keeping in mind the factions historical expansion and policies:

General Rules:
1: Only a family member can lead major armies. Small regional armies/garrison forces can be led by captains.

2: Sieges: Don't attack settlements until the last turn of a siege or ubless the enemy sallies on the last turn. (Historically, most settlements were starved into submission, although there are a few notable exceptions.)

3: Never use main battle units for prolonged garrison duty.

4: (As I usually have modified my installs to use 0 turn recruitment) Disband uneeded untis when not actively at war.

5: Never auto calculate battles

For added enjoyments, I use generals view camera. That'll really test your ability to command.
