You’ll have to take it with a grain of salt if you don’t speak moon, but according to this Twitter post from one of the devs at CyberConnect2, a .Hack//G.U. HD remake is on the way. My brother, however, does speak Japanese, and he confirms that’s exactly what this says. The G.U. series is like a sequel to the original .Hack games with, IMHO, a far superior story and more interesting world. However, in the efforts to expand what should have been three games into one, there were several lengthy (and boring) arena segments in each title... I hope these are removed for the re-release.
Also, my inner teenager may still have a soft spot for Atoli, one of the most compelling female characters in any video game.
