Im holding my finger crossed, that i will live to the day we get "matrix-like" games and i could participate as a survivor in zombie infested mmo. All the coolest things of zombie apocalypse without the bad things like getting eaten alive or seeing friends die... Just my fire axe and the shamblers. "Leeeeeeeeeeeroy Jeeeeeeenkiiiiiiiiiins!!!" ;D
Actually simple mmo concentrated on survival, supplies gathering and realism would be a blessing. Looking forward to Deadshed as well, but i hope you will not abandon Zafehouse, the system surely has potential.
Urban Dead, google it.
