The whole .hack series is split into an anime tv show called .hack//sign, Four video games called .hack//infection- .hack//mutation- .hackoutbreak- .hack//quarantine and four DVD OAV's called .hack//liminality. Theres also another anime series called .hack//udeden or .hack//legend of the twilight bracelet. They all connect to form one really big (and expensive) storyline. anyone else heard of these?
