hmmm... Mario the movie. that'd be worth watching.
It was entertaining, well there are a
lot better movies, but just because it is Mario and Luigi it is awesome.
And to the general conversation, there really hasn't been a good movie > game game I have liked. Well there is Star Wars Battlefront and the second one, but they are not just one story and I did like Batman Arkham Asylum but the same thing again, it is not based really off of any movie, it's really just bad guys from the comics but into a game.
So I think that the Avatar game will most likely just be like any other movie > game, they try to follow the movie's story but it's too short for a game so they add a bunch of other stuff you have no idea what it is.
