Attack on Titan is an space opera in the year 3032. It takes place on [i]Titan[/i], one of Saturn's moons, where a rebellion against the Terran Union is taking place. It's dramatic and sad and full of character deaths, but unlike Game of Thrones it actually has a coherent plot and is going somewhere. Also, the space ships aren't coming; they've already arrived and they're already bombing the moon.
