Every system and quirk that the series has acquired over the years clatters around in often nonsensical ways, and if you're new to the series - or if Monster Hunter World was your first taste - it's a game to be played with a wiki by your side or, if you're lucky, a patient friend familiar with Monster Hunter's many foibles.
This is a more primitive spin on the series, and the gulf between Generations Ultimate and World feels a lot bigger than the 18 months that have passed since this first came out in Japan might imply.
