This is one of the few times when an anime was so good that I found nothing wrong with it besides a few nitpicks here and there
You would like this anime if you like:
Mindgames (Death Note, Code Geass, ect.)
Comedy
Some Fanservice
Games (Chess, Poker, ect.)
There wasn't a single moment where I was bored.
This anime made me think at times, be amazed at times, and be laughing my ass off at times.
The art style is one of the best I've ever seen.
Don't read past this if you haven't finished the series.
The battle with the war-beasts at the end was GREAT! The action scenes where animated perfectly! Just when you think all is lost you find out that they planned THE WHOLE THING! I loved that!
Now to wait for NGNL season 2... hopefully it will come out in the next few years rather then when I'm 100 years old...
