There are tones more you could think of but you get the idea.
Who knows if it would be possible to implement any of these, but i do remember Dan Stahl saying on one of his last radio interviews that he would love to see something like this one day. Personally i think i would be alot better than sticking a Romulan or a Cardassian faction in there. What do guys think? what other occupation ideas do you have?
