A genre that Sword Art Online has dominated, now has some competition. They have done an amazing job in my opinion, whilst similar in that the human consciousness of characters are trapped inside their game, death in the game means respawn, not permanent death. And the NPC's have become self aware. They have spent a lot of time explaining and developing the world in which they are now living. Only thing I can say as a criticism is that the collection ends too soon. You will be overly eager for collection 2. (It can't arrive soon enough for me)
