Of all the games in the world, the group loosely classified as "massively multiplayer" or "persistent world" games have the most unexplored potential. They're among the oldest of multiplayer games; the very first networked computer users played adventure games similar to EverQuest, but comprised entirely of text. And with the advent of graphical interfaces, these massively multiplayer online games (MMOGs for short) may someday change the way we live and communicate online!

...at least, that's the promise. In the meantime the genre is trying to find legs. Are these products games or are they services? Should they be complex or simple? Should they cater to niches or mainstream audiences? How should people access them? The Game Developers Conference gives game developers the unique opportunity of stepping away from their current projects for a couple of days to put their heads together and hash out the answers to these problems.
