After watching attack on titan back in 2013 and again a week ago , i was left wanting for more or something similar. I was always a sucker for post-apocalytpic/sci-fi/fantasy sets in movies/series and now in anime. I have already watched full metal alchemist,knights of cydonia,god eater,heroic age,evangelion and many years ago the first anime i completed : claymore. I would recommend to anyone who perhaps was introduced to anime with attack on titan to watch full metal alchemist , not because of any similarities , if there are any, but because it is a pretty good anime with nice characters and interesting plot. The anime closer to attack on titan is god eater .Not that good but still entertaining enough. What i am asking are recommendations of good anime in that direction.(post apocalyptic setting + good story obviously).
