I would be insanely MAD if I don't admit and sound my utter interest in this concept. I really haven't been this interested in an RP pitch since an advanced RP called Soup Factory something. 

COUNT ME IN.

Though there is one little thing I didn't really like, the mention of other fandoms, I mean you got a pretty great-possibly immersive- world here. Populating it with pokemons, Marios and Clouds will take away the awesome Ultra Fantasy-Scifi feel. I am sensing Planet of the apes (original classic ones not the Mark Walberhg or Franco rubbish, sorry) , Bulletstorm, The Last of Us and oddly Star Wars. 

My suggestion: big no to cheesy and famous fandom characters.
