Garbage. Virus core grinding was already pretty annoying with how the data drain mechanic works but in this game it's particularly brutal. It feels like they ran out of story content and just threw all the grindy crap at the end of the quadrilogy. Combine that with exceptionally annoying encounters with mobs that make use of the most annoying status effects and ya got a real pain in the butt to play.

I find the end to this story to be highly disappointing and uninteresting, which is a shame because the first three did a very good job of capturing my imagination and making me want to see more of this fake MMO world. A complete fumbling of a finale. Worth playing if you played the first three but once you finish it, you may regret your decision to play the quadrilogy. For those nostalgic about fake MMOs or the .hack franchise, stick with the GU remaster.
