...It's a standalone expansion....a lot of games do this....and the MH series is one of them, get over it. And yes, Tri introduced a LOT of new stuff into the series. Just like how MH4 did. All games usually get a G game, and they almost always introduce more stuff into the series that the previous game didn't have. (3U's Blast element for example)
