They have now finished the GGO (Gun Gal Online) story arc in season 2 of Sword Art Online and are about to roll out the next one, Caliber. They did the same thing in season 1, where the first story arc was a Clear-the-Levels dungeon quest, and the second one was a Save the Princess game. While I think they could have actually broken them into 4 separate segments, they chose to do them in groups of two. I am really enjoying the Anime, almost as much as I enjoyed the books by Reki Kawahara they are based on. The other set of books he created, sharing that same universe and also turned into an anime series, is Accel World, which I am also enjoying watching. If you haven’t seen them yet, take some time to check them out; I think you will enjoy them.
