I actually narrow the definition to include a broad set of these games. Here are the qualities I use to define it: 2 Teams of a set number of players on each side (5 on 5, 3v3, 10v10) A commitment by the players to play a full round of the game, start to finish. A full match, if you will. Players choose from a variety of playable character or customizations, which rely on player skill. Extreme emphasis on team work. By these definitions, World of Tanks is a MOBA, but WoW and Starcraft are not.
