James Cameron has told G4 that "fanboys" calling Avatar a rip-off of the Halo universe need to look a bit closer at the source material.
"The funniest thing is when some of the so-called fanboys get up trashing Avatar for looking too much like Halo," Cameron laughed.
"It's like... pay attention. If I'm referencing anything, I'm referencing the source work for Halo, which is my own stuff.
"So I get to do that. Nobody else gets to do that, but I get to do that. My rule, anyway."
Bungie has admitted numerous times in the past that Halo was inspired by Aliens, which Cameron is aware of, so the fact that each resembles the other becomes pretty much inconsequential.
However, there may be more Cameron games in the future, as he told X-play that he's got "a lot of stories" left in him,, but not "enough time to make them all as movies".
Avatar: The Game's been out since December 2009.
