Like other media in the franchise, .hack is divided into novels, mangas, games, animes, and practically, one complements the other, not being 100% an adaptation. With hack//Roots, the difference is that it presents a mystery and, definitely, develops this mystery, you feel as if you are also inside the game and want to go after the answers. Like everything in the franchise, the soundtrack is a highlight, easily becoming an album to listen to on a daily basis while doing tasks at home or at work. The anime also develops the complementary characters well and not only the protagonist, I recommend it more, for those who havealready consumed something from the franchise, or are thinking about starting it.
