* NoExportForYou: The one-episode sequel OVA, ''.hack//G.U. Returner'', has not been localized officially and there is no indication it ever will be. It's a real shame, since it clears up a '''lot''' of confusion in the ending. The games also never saw a release in certain parts of the world.
* TheOtherDarrin: The entire English cast changes between ''.hack//Roots'' and the G.U. series. Roots was dubbed by The Ocean Group in Canada while G.U. had dubbing done in California.
* RelationshipVoiceActor: All over the place; to the point where ''TransformersWarForCybertron'' brought back at least half the voice cast.
