Our survival server was like this for awhile. It's a lot more empty now (school, creative/adventure popularity) but for a little while it was the place to be. We use Factions and a few other plugins on the server. Over the course of a month my faction, Shadows, systematically destroyed almost every other powerful faction. Everything went according to plan. The people in my own faction played their own roles well: innocent member, mad dog on a chain, etc. I've never had an experience go as well as that month did on our survival server. We "won" hands down.
