OMG I've wanted a Titanic world in Kingdom Hearts forever!!! Just imagine Sora running on that beautiful deck of that Grand Ship? Now that Disney has acquired Fox, maybe it could become a reality.
I've even created a World Map, Logo, and Keyblade. I call it The Ship of Dreams. Rose's Heart of the Ocean is the Keychain, and it will be massive with the longest reach. About the length of Sephiroth's Sword (maybe longer!!!!)
