Maybe because 1) It didn't gain enough popularity?
or 2) They actually asked for permission?
Come on Blizzard can't sue every single thing that copies them, they do pick their battles, I am saying if this MOD becomes popular like DayZ popular it will instantly die, Unless OP, Larian and Blizzard can all come to an agreement which I doubt.
Are you seriously denying the fact that outright copying a game is illegal?
I am just saying that OP is doing an awesome job but he should steer clear from the Diablo series, and make it his own original work. Geez
