I disagree about Star Wars, not least of all because it's 6 movies and counting. It's a huge, multi-planet universe so that makes it difficult to pin down locations, not to mention a host of characters from different eras. Marvel is, obviously, ten times worse than this but they're both just completely wrong for KH. I mean, how would you honestly decide which locations and which characters to restrict Sora's interactions with so it doesn't eat up the bulk of game time? It's just not feasible.
I have to say that I agree with this. At least with Final Fantasy characters they've already proven a great deal of success with working them in without just mashing things together horribly. Pirates of the Carribean, while it worked, it was a bit of a stretch. And Tron's world worked in the 2nd game, but in DDD? *Shudders* Just friggin leave it out already.
I could almost see Oniya's about Star Wars since there IS the gummi ships, but there would have to be some kind of explanation for the new enemies that we would face. With all games it's been heartless, or nobodies, or unversed that you come face to face with while on the gummi ship. Throwing in some elements of Star Wars might work somewhere down the line, but I really just don't think it has a good place in this game. And the same with Marvel. There is SO much history and too many characters to work in. Even with Final Fantasy characters they've limited who they've brought in and from what games. They haven't just taken a whole bunch of characters from each game in that franchise they've slowly worked in characters. And most of them, with the exception of the 2nd game, have had to do with FF7. So as far as FF characters go they haven't just taken a whole universe of games and tossed in a bunch of new characters as they would be by even trying to fit in Marvel for one. Maybe somewhere down the line with a new storyline they can find a good way to work in Star Wars and Marvel, but just throwing them in with the end of this particular arc? That's why its not a really good idea in my opinion for this game. There's no real tangible history that would make the fans go "Ohhhhhhh, so that's why!" and feel like the reason was justified correctly for those worlds.
Once again, that's just me as a long time fan of the game. I think that without game just throwing new things in because they might be cool or awesome to just be in the game isn't a reason to actually do it. Especially with such a loyal fan base like this series has.
How would Final Fantasy fans feel about suddenly seeing Donald or Goofy in the game? It would be... weird and probably not feel right. Hopefully that makes my point a little better since I went another rant. ^_^ ;;;;;
