My friend is playing with around 400 hours on Wii U (I only lasted 280 hours).
I myself have only the 3DS version.
I haven't played as much to have a Brachy Armor but I have the most overpowered bow and killed several Devilhjo's.
now with MH4U having Online Multiplayer on the 3DS I might play longer. And I probably will because the story mode starts with a freaking Jhen Moran tutorial battle.
Best. Tutorial. Ever.
