Besides, KH's story is BS anyway. It's so confusing you don't know which is first.
The Same's been said about FFXIII's story - I don't think complexity of a story is at all a bad thing - most of the time the inablility to understand it fully is counterracted by playing it again a short while after. If anything, KH's complex story only adds to it's appeal, it's not written to be completely accessible from the get-go.
I like the systems of the portable KH games a lot, but they're a lot less 'free' than KH2's system is. Also, combo's in the KH games are generally done by mashing X a lot (sometimes square depending on how many ablilites you have/how much you understand the battle system)
How many times have Roxas and Riku's design been used?
Well, Roxas' heads' design has admittedly been used twice for two different characters - but it was used as a plot device, so you can't really blame nomura for doing it. To my knowlege, Riku's design was only ever used for Riku. If you're referring to Vanitas, the similarity was also used as a plot device, and he was still redesigned slightly. You can't honestly be trying to say that the KH series lacks creativity because there is just no way.
...Not that I'm trying to passionately defend KH or anything. xD
Well, I am currently playing Kingdom Hearts, the first one on PS2, and I don't like it so much. I prefer 358/2 Days or BbS.
I heavily reccommend sticking with it so long as you make it to KHII. In my rather biased opinion, KHIIFM+ was the best game for PS2 ever
On the idea that it was aimed at kids, I think it was supposed to be aimed at a really wide range of audiences, not just kids. Obviously, they use some Disney elements to get the majority of children on board, but the age of the Disney films they incorporated allowed them to create nostalgia in a much wider array of people. Added to that, I think some of the aspects of the main story are pretty out of reach of young kids anyway. I dunno really, just my thoughts.
As you can probably tell, I am/was a bit of a KH fanatic. Haven't played any of the games recently though.
