For .hack I own

.hack//sign anime series(whole series. 26 epsiodes + bonus 2)
.hack//infection(with liminatlity disc)
.hack//mutation(with liminatlity disc)
.hack//outbreak(with liminatlity disc)
.hack//quarantine(with liminatlity disc)
.hack//legend of the twlight(all 3 manga volumes)

I really think the whole history of the series is fantastic and pretty imaginative. In everything they really fleshed out the charaters and slowly dropped hints as to what was going on and why through out the anime and the games. A lot was revealed in Liminality 3.

I took me a while to get into the games but I was working at gamestop and just kept giving it a chance. I just kept coming back.

I have seen the .hack//legend of the twilight anime but it sucked big time. It forgot its purpose and became too serious. They should have just kept it a manga which was really great and was never very serious at all. Pretty funny and light hearted.
