Nana code geass got some nicepoints... makes it better than naruto, bleach, fairy tail, one piece (it has a planned ending mainly, lol.)
But yo, I finished fate/zero and it was nuts!! Huge disappointing ending tbh, I was hoping for something more conclusive, but I shall not speak more of it... hate to spoil for someone who hasn't seen it. I need more material! Nice suggestion spoofaloof!
