But older Pokemon aren't Nostalgic to everybody. Heck, to some people they don't have any nostalgic Pokemon because they're still kids.
Also, what generation does nostalgic go under? Because for me third generation is nostalgic but to a lot of other people it's not.
And it's not really a matter of which you like better older or newer because they're were a good deal of old things I liked and disliked, same goes for the new things.
When you simplify something this much and use a word which could be applied to different Pokemon for each different person, you can't ever get a clear idea of what individual's taste are or the general consensus is.
