Pick something that fits. A title doesn't much interest me. 

but as an example. I've named 

Fantasy Rp: Imagined World of Allaria. Which references the map. 

Zombie Rp: Dead Man's Hand - a reference to dead things

Psychological Horror: Butterflies' Wing - Reference to the villains fear. 

Bleach RP: Rising Stars - reference to the new generation of Soul Reapers
