Collector's/Limited Editions & Pre-order Bonuses?
While Capcom has yet to reveal if a Collector's/Limited Edition of Monster Hunter World will be released, we have seen some in the past.
Here is a list of all the US editions with a Collector's/Limited edition:
Monster Hunter 4 Ultimate (Nintendo 3DS)
Japan has seen many more of these "special" editions than the western market, here are a few:
Monster Hunter Double Cross (Nintendo Switch)
Monster Hunter Double Cross (Nintendo 3DS)
Monster Hunter 4 (Nintendo 3DS)
Pre-order bonuses for Monster Hunter games, in the west, have been almost non-existent unfortunately. But in Japan, there would be a sort of "Day One Edition" where you would get codes for free Nintendo 3DS themes, but only redeemable on a Japanese system. There was one US bonus that was excellent, for Monster Hunter 3 Ultimate, where a free copy of the E-Guide was given! Strategy guides are another rare accessory in the west, where as Japan would get very extensive guides will all the games technical information.
