The Guild is a fictional example; there at least used to be a Penny-Arcade World of Warcraft guild; I know that in games that I play I regularly play with people that I would like to associate with outside of the game, especially people I know in real life.
Groups with a social focus have a different status in the game, but they do exist in large enough quantity and can be satisfying if people are about equally competitive.
