I'm not expecting many(if any) who have because it only shows at 4am on saturday mornings. But anyways, what its about is alot like it's predecessor, .hack//SIGN, in the fact that it compleatly is shown in a virtual world. The genre is kinda different from SIGN, its more of an action anime than a psychological anime. I suggest you watch it if you have a DVR or tivo or something like that. If not then watch it on youtube(if they haven't gotten to it yet :( )
