Played for two years, I know that is shorter then some, but I believe I at least have enough experience to... understand your point. About leaving the server, and what you have spoken about concerning antagonists. The methods you have suggested in utilizing MC mechanics and PVE mechanics is clever. It creates an air of mystery, free interpretation, and many other things.
I know that should one look at this profile it will argue against me playing for over two years, but... I had to recreate. Anyway, plus 1 indeed to such an interesting idea.
