Since the original Peace campaign is too easy and very exploitable, I present you a tweaked version of it. The changes I've made.
- Higher requirement and lower time limit when I found things too easy.
- Edwin attacks Sir Grey with somewhat bigger troops.
- Edwin presents a greater challenge during the sword production race. His popularity is less likely falls below 50 which would make him unable to produce further.
- Capped gold at certain points due to the game fails to take estate taxes into consideration. No longer will Sir William's "practically empty" treasury hold 6000+ gold...
- Food cap in your extra estate prevents the exploit of sending your food there before the quest of feeding Sir William's estate.
- On the last mission, royal food is set to 0 in all estates not just yours, preventing the exploit of hoarding it early on.
