So what would be cool is if after u beat the (hopefully) long, incredibly hard story of Kh3 u unlock Riku's Mini Story that either takes place during Kh3 but for what Riku does off screen or can show his story throughout like KH1 or after to show maybe in KH1 his traveling to worlds in search of Sora (before he finds him in traverse town of KH1) and his missions for Maleficent. Something like that where we get to continue playing and maybe his story would be a little tougher since it has to be unlocked. And the worlds could be different then what Sora went to in KH1 or any others. It would definitly be fun and explain possibly alot about what he did during that time or we could even do a mini mickey story of his journey through the Realm of Darkness in search for Kingdom Key D. That would be fun.
