At first, Log Horizon seems like just another .Hack, a story of a group of players that get locked in a MMORPG that fully simulates reality(Yes! the original idea was not from SAO). But here, instead of despair about how can they leave and the fights around that, the story focuses a lot more in how to make a place with this weird set of life conditions into a home. That leads to a very unique story inside a known concept. Also, this anime has a rarely convincing “super smart protagonist” that is very cool, and his main friend doesn’t even need to be super stupid to reinforce that.
