I don't plan to change the auction part of it much but the matches themselves will be totally different.
There will be 7 kingdoms.
Qin, Chu, Qi, Zhao, Wei, Yan, Han.
Unlike how COK was previously this time you can have multiple wars at once. For the sake of simplicity lets say up to two wars max.
Battle size will be random: 50k skirmish, 100k mid size war, 200k large scale war, 300k all out war or something like that.
Opponent will be random.
Location will be random
The war can be offensive, defensive or neutral.
Now this is when it gets interesting. You will have to fight on multiple fronts so you cannot just put all your generals into one basket.
There are severe repercussions for lets say putting Heki alone in charge of a 300k army. You will get crushed pretty badly and your kingdom will suffer.
The matches will be simple. A one paragraph strategy, deployment and nothing else. People will vote, give a reason (doesn't have to be complex) and will say how decisively one person won the war. Based on the results one kingdom will gain things and another will lose things.
Every kingdom could start off with something like:
In an offensive battle you can't lose territory but it will be harder to win.
I also want to add a "loyalty" stat. Basically guys like Ousen, Gekishin and Kanki can be persuaded more easily to join another kingdom. If your kingdom is weak for example and you suffer a bad defeat they may defect.
This is it for now. I will round this up more later. I think killing generals could also be a thing too and maybe politicians can be involved.
