I also prefer settings like the Shin Megami Tensei series, and when the original Kingdom Hearts was released I was quite sceptical about an RPG being centred around Disney.

But after many good reviews appeared I did purchase the game and was very surprised about how good it actually was. It wasn't childish and definitely not easy. Young children would not get far at all in these games. Also although they are Disney themed, they are done very nicely and each world themed after a Disney film or cartoon works very well and is is even better if you know the film or cartoon each is bases on as they have added a lot of nice little touches to each world.
