I posted this idea in another thread of this sort, what do you guys think of it?
What about this for a concept (bear with me, this could be a long post):
Anyone who's played an MMO will probably be familiar with some kind of Alignment system. if you kill players (PKing), you becoem more "evil" aligned. Liek doing bad deeds int he game Fable.
What about a double alignment system.
System 1: Depending on how you act, what you do, how you behave etc you are aligned as evil/neutral/good. Just a typical alignment system.
System 2: A kind of alignment that measures your "Strength of Heart". Perhaps succeeding in hard quests or overcoming hard times would make your heart "stronger".
The KH-MMO could have a limited number of Keyblades in existence. Perhaps 1-5% of the players. A player would start their quest with a normal weapon of their choice, if they are fortunate enough to come accross a random Quest Event - an Awakening - they would earn themselves a Keyblade if they showed a strong heart (ie conquered the quest). From that point on they would be a keyblade wielder.
However, if they were challenged by another player with a similar "Strength of Heart" alignment (this would be judged by the keyblade wielders Heart Strength +/- a certain value) then during the battle, the keyblade could lost to the other member. The original keyblader could still win the keyblade back under similar circumstances, or could try and claim anothers' keyblade.
This would avoid there being too many keyblades in the world.
