I think they'd have to be like specific command posts though. The outside town will all be PVP but there would have to be some Non-PVP areas to keep it a town. Like a shop, bar, or whatever. If it was one big room it'd be too much like a normal tower. Hell, if it was like that it would be a normal tower. And if you killed all guild members in order to conquer it would be King of The Hill. I like the "Good" baddy idea. They would probably be against the people who own the fort though but helping people attacking like "rebels" wanting to overthrow them. Yet there would also have to be some elements so it could function like a normal town as well. Like Onnet maybe.
