I am going to start getting into the coding mechanics of this game, I been only playing for about 3 months and since then, I have been more and more wrapped in it. I have done some small mods to Fallout 3 and Morrowind in the past, so I am pretty sure I can do 'SOMETHING' to this game, with all that being said, what you have mentioned
Bombard Reduce the enemy food storage by a randomized number, or make them 10% more likely to surrender. No battle
scenes/catapult animations needed. "
seems more than feasible within any working mod.
I'll see what I can do but being realistic, it might take me about 2 weeks before I can personally accomplish anything. (Work, gf, etc) but I'll look into it for you. I'm inspired.
