Sword Art Online Season 1 easily climbed up the list of popular anime titles of all time when it was released in 2012. There are a lot of factors that contributed to its success but possible the most obvious one is its art style. Sword Art Online introduced a refreshing feel. It’s as if every scene is carved out from all our expectations of what a fantasy world would be. The sceneries and overall beauty of the fantasy world is just a small part of it. Both the main and supporting characters were well thought-of. Their equipment and skills were carefully laid out to match their personality and affiliations.
