Man, I started this thinking there would just be a gentle trend toward liking earlier gens and disliking later gens, but this is stark.
There are plenty not on this list that I like but aren't favorites, and plenty I dislike that I can tolerate, but I really outright hate a lot of Pokemon...
Background: first game was Blue when it first released at 9 years old. Never actually played X/Y, S/M or S/S.
What's your spread like, /vp/? And where/when did you first get into Pokemon?
