In my usual Pokemon escapades, it took me far too long to finally see the credits of Pokemon Y. While the other games could just be excused by their sheer amount of content or even some grinding, Pokemon Y took me months to complete because of sheer boredom.

The personality, story beats, and challenge of Gen 5 is gone.
The expansiveness of Gen 2/4, vanished.
What's left is a member-berry salad of half-hearted nostalgia bait, fueled by a boring story with incredibly annoying characters. Everything culminates into an experience that's too easy to remain engaging on a gameplay front, and too dull to hold interest in its narrative.

I have negative interest in doing any of the "post game," honestly considering just jumping straight to Omega Ruby to just rip the bandaid off.
