Everyone will just be attacking eachother, how is that fun?
A. You are free to attack whenever and whoever you want, but there will be consequences. There are laws in the world to follow or not, this is your own choice to make. This may sound like a quake match for newcomers but it is not. There is a system that detects your action in the game that hopefully will balance PVP in an equal way it worked very well in UO. Playing a murderer will be a risky, hard life and they will probably get many enemies as in other players on the good side and from guards in the game. New players will be protected in towns and hopefully by other players.
