Well the original ones, Infection, Mutation, Outbreak, and Quarantine were pretty cool but I like the G.U. series better. The battle style is different and you can use more than just the skills of a Twin blade. As Haseo, who is an Adept Rogue, you can learn to use a giant broadsword, and a huge scythe. But as Kite in the original four you were only able to use twin daggers. Plus you didn't have much stuff to use. G.U. is a major step in the .Hack series and I love it
