The large acronym stands appropriately for Massively Multiplayer Online Games. Yes, quite the mouthful. These are a combination of metaverses and video games. They are video games because you play as some type of character and you go around on adventures and your character evolves as the game goes on. They are metaverses because you play as yourself, a character you create and is uniquely yours. Not only that, but unlike a video game, MMOG's have no end in sight. there's no mega-boss to defeat and beat the game. You play in the universe with other players like you. The adventure continues forever...

Or until you stop paying your subscription fees. But for our frugal friends out there, there's a few of them that are absolutely free.
