http://kotaku.com/5916888/kingdom-hearts-director-wants-to-add-pixar I can see a lot of Pixar worlds working really well in Kingdom Hearts - especially Toy Story. We could have an Andy's House world with Sora reduced to the size of the toys. Maybe even throw in Zurg as a boss or something. Monsters, Inc. and A Bug's Life would probably make for really good worlds too.
If I don't see Ratatouille in the next Kingdom Hearts game, I'm going to be extremely sad. /furry I think that a Toy Story world would make for a fun KH level. So would Wall-E.
Toy Story would be amazing. It would work so well in the KH universe, I think. They'd translate very well to the format of the series, especially in the format KH2 took where you return to a world after the halfway point of the game to do more plot. (Or even putting it in multiple games to cover the basic plots of the movies would work too.) And there are so many different locations used in the movies that it would even work well with the format KH seems to be going down lately where you play as multiple protagonists in different areas of a world. I've wanted this for a very long time. Buuut various people connected with the series (including Nomura himself, I believe) have also been saying "I'd love to add Pixar!" for a very long time, so I don't really pay much mind to this news, haha.
I think all of their films would work more or less: Toy Story- Lots of interesting characters and settings A Bug's Life- See above Monster's Inc.- See above Finding Nemo- Cool environment and characters, not sure how it could be incorporated into the game though The Incredibles- Characters are not that interesting but a segment on Syndrome's island could be neat Cars- Probably the one that won't mesh well at all in a Kingdom Hearts game Ratatouille- Would have to be from the rats' point of view, which would be cool WALL-E- For some reason I don't see how this would work. The deserted Earth would be boring, so the level would have to be the space station and I'm not really sure what you would do there Up- This would be great. Carl Fredricksen, Russel, and you in the jungles of South America. Cool Brave- Probably the most likely since it's their most recent film
