I think with maturity comes an appreciation of what has value; be it literary, comedic, you name it. It may just be my opinion, but I think that all Pokemon has going for it in this way is A) ingenious gameplay (or at least it was clever when it first came around) and B) nostalgic value. I hate to burst the bubble of all you fanboys (and girls) but Pokemon was never known for story value, the graphics have been sub-par (especially in the DS games), and the anime is terrible and has been for quite some time. Game Freak is pretty much playing up the fan base's loyalty by putting as little effort into new games as possible in order to keep introducing minor "improvements" to the same old same old, put it in a new box, and sell it to you for thirty dollars. Nintendo is known for its innovation, but sadly the same cannot be said for Game Freak- at least when it comes to Pokemon. If you want an ingenious game in the range of what Pokemon should have been, go play Spore. Or Nintendogs.
It's all my opinion of course, sorry for the length and the way it turned into a rant. No rude replies please
