Well recently I met lot of people who said that X\XX were spinn-off... but they didn't give me any proofs for that. So I'asking here, it was offcially announced that X\XX are spinn-offs?
Personally I doubt... I mean they are clearly setted in the same universe of all the previous main games and apparenty chronologically after MH4U.
If that isn't enough to be considered canon to the main storyline I don't know...
Thanks for the attenction.
