Would anybody want to RP the Orkz from 40k?
As a faction we'd be dedicated to being Orky, violence, and personal wealth acquisition; in that order. Organization would be pretty simple; everyone does what they want most of the time, though piracy("freebooting") would be encouraged, with the organization in general trying to build up its war machine.
The one exception is when the whole faction goes to war, which is done when the Warboss feels it's time for a WAAAAAGH!, which amounts to him telling all orks everywhere to go kill a particular thing or set of things. The faction's combat doctrine will be based on material superiority, logistical flexibility, and extreme disregard for personal safety.
I myself love the idea of capturing ships, retrofitting them, then painting it red and welding spikes on it to make it look more orky, the rest is just an excuse to do that. If it appeals to other people though I think it could be a fun way to stir things up. I foresee entertaining confrontations with the Borg.
