Halo fizzled, Bioshock is treading water and they think WOW is going ...
to be a successful franchise. GTFO. Halo had the most potential to transition to the big screen, as it already had the story and protagonist not to mention a major fan base. It is seemingly dead. Bioshock has maybe a better story then halo but is not quite as established but still i imagine might work as a movie. Gore has apparently dropped it, and no major announcements since.
So they think WOW a mmorpg is going to be successful. Right, first off your main problem is there is no centralized story as far as I know, so there really are no characters to pilot the movie, they can make up some but in the end it will just look like a cheap knock off of LOTR, and i cant imagine any story they come up with will be anything impressive. This is not a direct comparsion, but several animes made based on mmorpgs tanked like maple story. So you think its gonna work as a movie franchise. Lol my friend, lol. WB must of gotten hit by a confudus charm.
