Goat Simulator is one of those rare gems where everything is done wrong in just the right way.  This Thursday Coffee Stain studios is releasing a patch to add an MMO Simulator mode.  http://kotaku.com/free-update-transforms-goat-simulator-into-goat-mmo-sim-1659639634

Does this mean you'll find hundreds of goat avatars running around trashing stuff?  Maybe...  but it's doubtful they're actually being controlled by other players.  That's a huge amount of infrastructure and effort I doubt Coffee Stain would be willing to invest into an intentionally broken game.

But if you've been feeling that the gitchy goat game doesn't have enough of a Warcraft feel... then this update is for you!  It's got all your favourite classes; Tank, Rouge, Magician, Hunter, Microwave.  I can't wait!
