masamuneehs:
Thnks. I'll take it into account.

Aeon:
While watching the previous hacks (Sign [Anime] , Infestation [Game], Liminality [Ova], AI Buster [Novel], Zero [Novel], Another Story [Novel], Dusk/Udeden [Manga]) is not a requisite, you will be missing a lot of elements.

Like who Tri-Edge resembles.
What is Data Drain.
The significance behind Delta Hidden Forbidden Holy Ground.
And most importantly... who is Aura.

As far as I've seen, the 3 new hacks (announced for now) .hack//Roots [anime], .hack//G.U. [game] and .hack//Jack [Ova] have a lot of references to those points I mention above. Plus new novels are coming out... (If only TokyoPop hurried and translated Another Birth [scheduled for june in USA] and Zero [non-scheduled] ).
