Therefore, let's do a general overview of what else came about from G-Saviour, and try to figure out just where it truly stands in the canon of Gundam.
The first to bring up is easily the most important of these other products. You see, G-Saviour was conceived as a three-part story, with each told in a different format. The movie was the middle part, detailing the story of how Mark Curran helped stop General Garneaux's mission to keep CONSENT as the ruler of the people. The game was the final part, detailing how Reed Fox helped bring about the end of CONSENT's tyranny by stopping the dangerous Project Raven led by the rebellious Commander Bais. That just leaves the first part of the story, which was told via its own three-part production as a radio drama. Broadcasting on December 28, 2000, the day before the movie debuted on Japanese TV, the G-Saviour radio drama told three stories whose events lead to the plot of the movie. Obviously, this is the only part of G-Saviour that wasn't performed by English actors first, so everyone is voiced by professional seiyuu, though some characters from the movie do make "appearances". Since I can't really experience these radio dramas for myself in any good fashion (mainly because my Japanese is too rough to enjoy it with just audio), I'll be making educated guesses as to what they may explain, based on the basic concept of each story.
