Why would you need an EBII version of the Spoils of Victory unofficial submod? IIRC, M2TW has a built-in ransom feature. I've never played M2TW myself, but I was watching my roommate play yesterday and he chose to ransom the prisoners of war after a certain battle. The enemy AI faction said they couldn't afford it, so the prisoners were automatically executed. I think this is a pretty good system.
