>>28380109Same, I don't really care much about post game. Once the plot is over, I tend to lose interest shortly after.
Honestly, I never even cared that much about winning the champion title, either, since it always just kinda seemed like something to do after you defeat the evil team/save the world/whatever. I still do it, it just seems like a step down in terms of excitement. Winning some title doesn't hold my interest as much as defeating some major villain's plot. By that time, too, I usually am set in my full team, so it's not like I even care much about the new Pokes that are accessible in victory road, either.
That being said, I rarely take the time to complete my Pokedex. I probably will this time through XY though, since I need something to kill time while waiting for SM.
