So, I really enjoy those player-driven RP's, as it gives the player a sense of accomplishement, and allows the GM to focus more on moderation. So, I decided to apply this idea to one of my favorite fandoms: Kingdom Hearts. 

[color=red][b][h1]The Story[/h1][/b][/color]
Everyone knows the legend of Sora, the great Keyblader who traveled the worlds, fighting the Heartless. However, fate had a terrible twist in store. Sora, the hero, went to face Ansem. No one knows what happened exactly, but Sora did not return alive from that battle. The secrets of the Keyblade became lost after Ansem flooded the worlds with darkness. Sora may have saved the worlds, but he couldn't stop the ultimate evil from taking over. After Ansem gained the power of Kingdom Hearts, he used it to wipe the Keybladers form existence. Only Master Yen Sid managed to escape, but it is doubtful that he is alive after thousands of years. Ansem has only grown stronger, and people live in fear of the Heartless.

However, Ansem is not unopposed. Organization XIII has also grown stronger, and their leader is not happy that someone else has obtained the power of Kingdom Hearts. Thus, the Nobodies have declared war on the Heartless. It is not unusual to see Nobodies and Heartless fighting several battles. However, the war seems to have stalemated over the last hundred years. Fighting still happens, but neither side is able to gain a decisive advantage.

In this war-torn world, the people hope that the Keybladers of old will return. However, each day, their hope diminishes as no Keybladers appear...

That is where you come in. Depending on interest, I may also let people decide to be a Heartless or a Nobody. However, the central plot point is a group of normal people who mysteriously find themselves warped to a strange tower after being attacked by the Heartless/Nobodies. Or, they could be caught up in the middle of the fighting by pure bad luck. Either way, they find themselves in the tower, where the spirit of Yen Sid helps them realize they are the next generation of Keybladers. After very basic training, they are sent to quell the war and bring Light back to the worlds. If they succeed, they will be the next Keyblade Masters. If they fail... things can only get worse.

As I said before, if there's enough interest, I may let people be a lesser Nobody in Organization XIII, those who are relegated to the roles of field commanders. Same with the Heartless. That all depends on how many of you want a player-driven experience. As GM, I will be there to nudge things forward if I feel the need. I'll also play important NPC's (Organization XIII's main members, Ansem, etc.), as well as bosses. This is still a work-in-progress on the story, so any suggestions are welcome. Oh, and if this gets too big, I may need a Co-GM or two. So... any takers?
