MHF-G is an online-only game for PC and XBox only. It is limited to Japan since the Taiwanese and Korean were both shutdown.

G2 is an expansion of MHF-G and was released/updated on July 10th. They simply have not released all monsters for this season/expansion yet. G3 is due to release later this year.
