I thought it would be interesting to post what I believe that would make cool new worlds to the Kingdom Hearts saga. Hera are my picks and why:

Gargoyles:

 Come on,who wouldn't want to fight alongside Goliath? It has a dark tone with a little of disney on it. The world could have a medieval side and New York city, cool gargoyles-shaped heartless and a ton of monsters to fight. I don't know if this world would have a princess but still.

A Marvel universe world:

 Yes please! How awesome it would be to play in any part of the Marvel universe, play next to the avengers and be able to "summon" The Hulk. With Guardians of the Galaxy on its way this world can go cosmic. The princess ... no princess haha.

Star Wars:

 Not so far away from possible! Think about a lightsaber keyblade, fighting alonside Obi Wan, Luke, heck even R2 D2! It would also be a good opportunity to do a couple of missions on the gummi ship, take down AT ST's, Star Destoyers, the Death Star! The princess of course ... Princess Leia.

A Final Fantasy inspired world:

 If characters from the Square-Enix universe have come to the Disney universe why can't it be the other way around?. A world inspired by places like Midgar, Gold Saucer, Alexandria, Zanarkand, you name it! Fight alonside a Moogle, Cloud, Zell, Vivi, Zidane. The princess of this world, I don't know could be Aerith, Garnet, Rinoa, Yuna ...

Which Classic deserves a re-make?

Let's talk about those games that we grew up with and that we wish that would come back. How would you like that re make to be? Would you change anything about it? Would you put something new on it or take something out? LET'S GO

1. Final Fantasy VII

My obvious choice. I wouldn't take a single thing out of this game, starting with the battle system because I love the classical RPG's. I would make it with better graphics (HD) and add a couple of new side quests.

2. The Legend of Zelda and The Legend of Zelda: A Link to The Past

I would like to see a full 3D version of these two classics. Deeper dungeons, expand Hyrule a little so that you may use the boat on The Legend of Zelda and maybe introduce a horse on A Link to The Past, HD graphics.

3. Chrono Trigger

I would like to see the same things that I would like to see on FFVII but they should keep the anime cut scenes made by Akira Toriyama.

4. Star Fox (SNES)

This game was awesome and unique when it came out back in 1993, introducing the Super FX chip. And since we haven't got a decent Star Fox Game since Star Fox 64, it would be nice to have this classic get HD graphics and a multiplayer mode and an online free for all.

5. Super Mario RPG

This game was freaking awesome! Mario + Square Soft (back then) what can you expect? Fireworks! This game needs better graphics and cool cutscenes. Maybe add a couple of new special moves for all the characters. It would be cool to see Mario using F.L.U.D.D or maybe summoning something out of the Mario Galaxy Universe, Giga Bowser would be a cool addition, Luigi …
