.hack// is kinda a whole slew of media... The first that came out was the anime, then they released the PS2 games, then there was manga, a chibi anime called Legend of the Twilight Bracelet, then novels, then more games such as .hack//G.U., and it goes on and on. There's even a cellphone game in Japan now called Twilight Dragon, or something, I think. It's kind of gotten away from me and I just dream of one day finishing the games... XD Because they mimic an MMO without actually taking you online, and you play a character who gets swept up in the mystery surrounding it all.
