I have watched the first episode of No Game No Life, Mekaku City Actors, and Akuma no Riddle. I've watched the first two episodes of Ping Pong and The Irregular at Magic High School. In all honesty, Ping Pong the Animation is currently my favorite this season. The first episode made me more interested in their characters than any other first episode I've seen this season.
I won't exactly rate them all, but I've also enjoyed The Irregular at Magic High School. I especially like the main character so far compared to all the others because it feels like he is doing something much more important that what is going on around him. I would like it if the show drifted away from the heavily implied incest... But that's probably asking quite a bit considering the majority of the main cast are voice actors from Oriemo.
Briefly on the others, Mekaku City Actors was interesting, but the first episode was really underwhelming. I hope that the show can get a bit more serious and drift away from the overtly shaft style of animation. I really was not a fan of Akuma no Riddle. I almost quit watching No Game No Life because it felt like it was far too overtly ecchi and I couldn't take it seriously an ounce. I don't think I'll continue it, but once they got into the game world it became much more intriguing. The idea that you can cheat your way to the top as long as you don't get caught was fairly unique.
Edit: I forgot to mention the first episode I watched of Black Bullet. The premise was interesting and the action was cool, but the characters felt very bland and uninteresting. I may or may not continue it.
