Sword Art Online Alternative: Gun Gale Online. Was a refreshing light novel which gave me a new point of view of the SAO Universe. Sigsawa Keiichi did make a great job in the management of the game described in the main saga (Sword Art Online) and in the creation of a complete new story with a goodly enough plot to be at the level of the series of Reki Kawahara.
The weapons and the setting were perfectly described with an enough amount of words.
The battles are related very well and it feels like a real battle royale.
The only bad point that I can remark of this novel are the illustrations, since for me they were a little dissapointing. But if for you they were good enough, it's ok.
(This is my first review, I will do it better next time)
