I don’t play Massive Multiplayer Online Games (MMOG), Massive Multiplayer Online Role Playing Games (MMORPG), or Massive Multiplayer Online First Person Shooter games (MMOFPS), but I bet everyone knows someone who does. My nephews play, my friends children play, and my friends play. MOG (Massive Online Games) are typically subscription based services that host massive amounts of people in worlds that give them an opportunity to play and interact with each other at any given moment.
