and at this page:  http://metalgear.wikia.com/wiki/Metal_Gear_Wiki       mpo stands as a spinnoff game, its it really a spin off? Just because it's a spinoff doesn't mean it isn't canon. Don't forget, the Resident Evil games Code Veronica, Resident Evil 3: Nemesis, and the Revelations games were technically spinoffs rather than main entries, yet they were undeniably canon to the story.
