Fate/zero is pretty much similar to Fate/Stay Night with its base story revolving around the holy grail war. What sets it apart is that Fate/Zero has a darker plot, more character development and a high degree of plot twists. Fate/Zero also has a very nice lineup of OST. Overall, Fate/zero is top notch.
I recommend:
○ Nyanpire (Cute and funny show)
○ AnoHana (GO. WATCH. IT. NOW.)
○ Working!! (Funny at most)
○ Shinryaku! Ika Musume (Just... XD)
○ Nichijou (It's just random)
○ Fruits Basket (It has it's funny and sad moments)
○ Keroro Gunso (JUST RANDOM)
○ Nurarihyon no Mago (IT WAS EPIC)
○ Gosick (Mystery and comedy)
○ Black Rock Shooter (Short but nice)
