i just noticed that kingdom hearts has a similar realms to a final fantasy tittle for instance in dream drop distance you visit the dream realm isnt that the realm tidus comes from in final fantasy x? in kh 2 i always thought that the items were materia 

I think its pretty obvious. lol

true took me awhile to put 2 and 2 together since they are basically the same title  

The Dream Realm is one thing, but I think you're looking a bit too much into the whole items/materia thing. Materia all share the same features: they're round spheres. The only thing that sets them apart are the colors. The items in Kingdom Hearts all have their own unique appearance.

Fool. Some of the enemies have similar names too. All the items are the same too. There is a lot more, I just can't think of any right now.
