MG, MG2, MGS, MGS2, MGS3, MGS4, MGSPW, MGSVGZ all have their titles acknowledged by Kaz and he gives information on them and the light is able to remove them.

While it doesnt answer if MPO and MGRR are canon they pretty much tell us that they are not part of the main series.

And Im not being funny but the Digital Graphic Novels on the Legacy Collection anyway are not games they are movies that show alternatives to the stories.

Exactly, spin-off =/= non-canon.

MPO and MGR as practically spin-offs and creative make, but given the sources and how they tie in to the major games's stories, they're still plenty canon.
