What is the Premise?
Keima Katsuragi is a high school student that is known as the "God of Conquest," the man who can obtain the heart of any girl. At least in Gal games. A Gal Game is a dating simulation game in which the end goal is normally to date one of the girls in the game. While this came out before No Game No Life did, he does share the mindset of the lead characters, as he was quoted to had said "Reality is just a crappy game" Getting a Challenge and a big push to do so. Him and his now linked partner from hell, a Demon called Elsie he now need to capture the hearts of real girls using all that he learn from his Gal Games.
What type of show is it?
Being a Comedy more so then a romantic comedy as well as a parody of Gal Games and Dating Sims, The World God Only Knows does rather well of not falling sort. While I seen people list it as a Harem show I don't feel it really applies here. Except for the 3rd Session the girls which he capture the hearts of and get a kiss from will then forget what had happen. Somewhat of a soft reset so that he could now focus on the next person. Although like some Harem shows, they don't spend a overly lot of time on any single romance.
Is it a Hidden Gem?
If your looking for a hilarious anime of an "Otaku Pro" going out and dating real girls armed with nothing but Game Knowledge then your bound to enjoy the heck out of this show. The premise of this show hides nothing from it's viewers. If you enjoy heavy comedy with your romantic comedy or enjoy Otaku humor (Such as what you expect from a show like Genshiken or Big Bang Theory) then this is worth a watch.
Rating : A Rough Gem!
An Anime Worth going out of your way for, for the right crowd.
