Looks as though an Avatar MMORGP is coming along with the movie sequels. Cameron:
"I think Avatar is a perfect IP for an MMO. It's a very, very big world and based on the first film, you might not sense that, but we're talking about an entire planet, an entire alter world, and in fact a universe that has other planetary bodies, as well, and other cultures, other life forms. Eventually people will see enough scope to be able to see how the MMO will work, but that's going to have to be launched…the timing of that is going to have to be carefully orchestrated with the release of the second and third film because we don't want to be giving away elements before the fact. And also I think one of the cool things about an MMORPG is that you have to have a lot more possibilities for characters than what you see in the film. The film is really just a leaping off point, so we've got to create a rich and diverse world that lives well beyond the films."Read the entire interview.
