There is a script in the exchange that replaces a lord if one is killed, it randomizes stats, renown, names, etc... Basically its the son to the lord that was killed, kind of similar stats but randomized a bit. I've been kind of reconstructing this code to hook it in with the extended prisoner chat, thing is you have to create a crap load of names in strings...but the cool thing is its culture specific. That way if you kill a sarranid lord it won't be replaced with a swadian name etc...
It would be interesting if there was a "commander" system, if the lord is killed then a commander, one of the lords friends or relatives, takes over the army, they would be weaker then the lord but still able to do most of the same things, and in spirit of Freelancer if you eventually get a high enough relationship with that lord then you become the commander. Furthermore you can make friends with individual soldiers, they work like NPC heroes but are killable and have standardized equipment. Also random lords have their sons in their party, and if you kill/capture the son then you get -50 relationship with that lord, vis versa if you kill/capture the lord.
Anyway, when is the release date?
