After posting some “not so bad idea” I think it’s time to me to post an idea that is pretty bad, I think.
Trustbuilding Problem.
Your lord can have support with every other playable character, but the only unit you can control is the lord and other unit who have support with him/her. The rest are controlled by the AI.
Kinda inspired by this AFK romhack AI.
It seems to be somehow able to be applied to other romhacks. Now I wonder if there is a patch to have (almost) unlimited support.
