You can "clasify" games with MMO when differ between network types as single player, multiplayer, online game,...
mmo referees to mmorpg in most cases which is a genre.

Most ppl do not consider games like Diablo, Call of Duty, LoL, Path of Exile, Hearth stone, and World of Tanks mmos. Although developers are starting to call them that.
