Characters you would have added, and what you would of had them doing...
Many of us good fans of the movie were undoubtedly upset at the loss of many of the characters from the movie, alot of which were proboably some of our favorites (I hate the Harleyquin demon being absent). There's nothing we can do to get them into the game, but it'd be fun to think of how they could have been added!
I would have added three (actually five, but the last kind of counts as one).
1) The Harleyuin Demon (obviously). I would have had him stand somewhere on the streets. He woul just stand at a street corner in the town square (next to his tayloring area). He wouldn't play a major role in the game, but if you spoke to him after maybe saving him from a hoard of skeleten monsters, he'd reply by telling you how thankful he is; and he'd promise to give you (Jack) a present. "But it'll be awhile... Come back later, and it'll be finished, okay?" he'd say. The present would be the hidden costumes you unlock for completing the game with good scores.
2) The Undersea Gal. There'd be a part in the game where Jack would be told by someone that he needs a certain item (key, map, etc.), and that the Undersea Gal has it. They would say that they couldn't find her, but they last saw her near a lake. Going there, you'd find her barely holding onto a rock, caught in a current. There'd be garbage and monsters polluting the water. The objective here would be to use your Soul Robber to latch onto her, and try pulling her to safety. The point here would be to sometimes let go of her (which would slowly pull her back to where you pulled her from) so you could run to the left or right of the platform so you could pull her out of the way of obstacles which would hinder your process.
3) The band members. They'd also stand by a street corner. They would give you the option to change your battle music, or the music you hear in Halloween Town square (just songs from battles, only instrumental). You could maybe only unlock them by saving the three (which would be scattered about) from large monsters. Like, maybe those ogers. You'd have to fight a large group each.
Anyway, that's who I'd include. I'd like to want them all included, but I don't wanna take everyone up. :)
