You know, you can PK and all on the 2002 server also. No rules against it. And you can try and become rich or whatever if you like. But you'll probably have the most fun if you roleplay, 'cause that's the goal of the server- that and some character stuff to make building it up a little funner.
But, if you wanna PvP, do so to your heart's content. If you wanna be a rich little hermit sad and alone with every item on the server, go for it.
Everyone wants to get ahead, but think about fun first and you could get a lot out of the game.
