Please peruse the evil Flash-based Official Site for one of the neatest ideas to come around in the gaming industry for a while: make the cartoon, the video game, and the comic book together.
As opposed to past situations where a game was written to mimic and existing cartoon or comic book, this was acutally actively the intention for Project .Hack from the start. How well does it pan out? I dunno yet. I intend to finish watching .Hack//Sign before I pick up .Hack//Infection or Liminality.
