My vote went for Friends-only multiplayer and playing with myself.
Erm, I mean, playing the single player experience.
Surely, I will give the public games a try after a while, but I am not too keen on it as in all the games with PvP element have been unpleasant experiences for me as I am not a competitive player and I get no satisfaction from it. Of course everyone else seems to notice it and harass me endlessly until I quit. I don't think I am doing anything that could provoke such a reaction. Unless that is the very nature of a PvP player, attack everyone on sight.
Of course if there was a negative impact on attacking another player, that might keep it down a bit... But then again, that is just wishful thinking as everyone will probably just point and ridicule me for even suggesting such a thing.
