In many respects, Generations Ultimate is the exact opposite of Monster Hunter: World. Where MHW is intended to be an accessible entry for beginners, Generations Ultimate is effectively an expansion pack. One of its key features is the ability to transfer save data from the 3DS version. It’s a tribute to old-school Monster Hunter, replete with old favorite monsters and familiar levels.
