The main character has flaws in real life and the game helps him to face those flaws, i really liked that about this anime.
I also liked that the main character is not overpowered in any way and there are no shortcuts for him at all, the point of this anime is that the game is just as "realistic" as his ordinary life so the challenges he faces are never easy.
It is a "harem" anime, with many females, and there are not really a male rival or best friend character in it, but it is not a romantic anime either, the anime focuses on choices more then building up strong bonds, so it is more like a learning curve for the main character about how to handle situations in the game and in real life.
This anime takes itself seriously but it has a good sense of humor too and it manages to keep you attention and excitement through the whole 12 episodes.
Fun, enjoyable anime, worth watching.
It is a 1st season and the ending is open so dont expect a full story, so you either watch it and wait for the second season or you wait till the second season comes out, but keep it on your watch list because it is good.
