According to Jeff Strain, co-founder or Guild Wars developer ArenaNet, basing an MMO on an existing film, TV or book franchise won’t lead to success in the genre.
"Even the big two [franchises] haven't lived up to their expectations," he said in a Games Convention Developers Conference session, and went on to point out that the top two MMOs are based on original worlds, unrestricted by the linear nature of products designed for other media.
He went on to add that most games fail because of the social nature of the genre, and because gamers rarely commit to more than one at a time.
