Nah, I've not written anything yet, but I have an idea bouncing around in my brain. Basically:
the year is 2015. The Pokemon world is officially screwed up. two years ago, the war to end all wars broke out between the various pokemon types. Over time, various types have made their alliances with each other and moved into various regions. The Grass, Bug, Flying and Water types have settled into Hoenn, which has begun to resemble a lush, tropical paradise. Kanto has not fared so well - it has been colonised by the fire, ground, rock and steel types and is slowly becoming a desert. Johto has become the one land where people still live in large numbers and is home to the Electric, poison, normal and fighting types. Sinnoh has become a no-go zone, filled the most dangerous and mysterious Pokemon - Ice, Psychic, Dark, Dragon and Ghost types. Each RPer will be playing as one of a group of trainers. These trainers have been selected as the best in their specialist type, better even than the respective gym leaders. Their mission is to travel into the region of their respective type to collect the seventeen plates. These plates will then be used to summon Arceus - the only entity with enough power to end this war once and for all.
