Well, I've been an MMORPG fan for quite a long time now, and I'm quite interested in games about it.
This is what I think (I have played a lot of games since I was a kid, so my opinion may differ to you who doesn't play video games)

Story(There might be some spoiler) - As much as I've seen, there seems to be a lot of similar situation as SAO (Sword Art Online). I won't say it's a clone, because there are major differences as well. And it goes well explaining about the Job/Class description for the viewers to understand.The story develops around the main character, Shiroe, a "genius" tactician. But Genius is not what I had in mind. Shiroe is somewhat an "average" RPG player, and his friend, chief Nyanta, an Action-adventure single player gamer, are the only protagonist that seems to know what they're doing, as well as the other characters, they are like newbies/ new players that started playing games. They make Shiroe looks like a genius, when his tactics are actually simple, he just speaks to much, over-explaining such simple and common tactic. And his enemy too seems to be a newbie, and doesn't know anything about the game's classes. Therefore, puts the average-Shiroe to look smart. And this isn't just me, I've asked a lot of people as well, and they say the same thing as well. And I'm sure you can't deny this fact if you're a game addict and have been playing games for long enough.

Dialogue - As I said before, there seems to be too many useless explanation over the series. Over-explaining thinggs so that Shiroe looks smart.

Animation - I can't deny that this Anime has great animation.

Entertaiment - There are some, I mean a lot of laugh-worthy jokes that they do all along the series. It's great and all, and the actions are pretty good as well. (show less)
