I own this anime and, it pretty much owns:D. I got into it because of the whole MMORPG theme lol brought back old memories xD I thought that was pretty shweet. But what I didn't get was...
Does it ever explain why Tsukasa faints whiles she is at her pc? Maybe a little too much to drink :animesigh :P. And when she is in [spoiler]the hospital does her father try to kill her? and why.[/spoiler]
Edit: I'm not sure if this should be brought back, it was a great anime and all if you like a good story line and it had a good ending, I wouldve liked it better if the damn hands actually touched at the very end... Like what if 2 seconds later the hands are like 3 molecules away! and Subaru just gets ran over by an 18-wheeler, like omgish we'll never know :((but that would be an AWESOME ending ^^). But now that I've gotten into more action anime, I think if I watched it now it would be pretty boring, Neon Genesis Evangelion has more action in episode 1 than in the whole //sign series. But i haven't seen the other .hacks or any OVAs
