I don't think you can really stereotype the largest video game fan base in the history of the industry. It's just impossible to group-up damn near everybody.
I would, however, like to respond to those who think that WoW and the rest of the MMOs are jsut a boring grindfest in which no sane person could find enjoyment with a list: Civilization, any of the early Sim games, Harvest Moon, New Horizons, GigaPets, et cetera. MMOs did not come close to inventing "grind," and they don't come close to having as much of it as the above. If one further defines MMO instances as grind, we can add any game, of any size, you play more than once to the list.
