[quote name='LeafPanda']I overall enjoy the .hack story. This is based on Legend of the Twilight Manga right?[/quote]
Not in essence, no. The .hack franchise is huge and there really isn't anything that is fully an adaptation of another part. In other words, the novels, manga, games, and anime are all a connected story or individual stories in the same world. Everything can be enjoyed on its own, but the first .hack anime will lead you into the original .hack game quadrilogy, which include the Liminality OVA series that shows what is happening in the real world during the game. The .hack//ROOTS anime is a precursor to the GU games. The novels and manga all fit in there as well.
[quote name='Moxio']It's unfortunate you didn't enjoy BoFIV... I felt it was a fantastic game with a very solid story (certainly better than FFVII/VIII/IX) and simple, but extremely satisfying gameplay.[/quote]
I loved the story, but hated the gameplay. It's one of those dividing games - some love it, some hate it.
