Second is a resources intensive no-devil game, where players have thousand of machines. When they get tired, they have all kind of chat rooms (chat rooms) and landscape attractions (named sims) with various themes. But it's just a big no-devil game.
That kind of camera control can be provided by HUD available freely on the market place, no need for a N-th client modification. I fail to see the interest of that kind of camera anyway, they often get annoying and fail to catch the action because they lack the intelligence to know what action IS.
