Well there is a lot more to it. For example king could be player or AI controlled.
There could be standard attacker vs defender.
There could also be 2 kings one in each team.
And if you played AA there could be something like escort the vip from point A to point B. Vip there was a lot slower and already injured.
So much possibilties I want to start kickstarter project to do this. Whos with me?
