Quoted By:
Gen 1:
-Team Rocket (team just out for money and power rather than trying to destroy the world or whatever, and they're not the same in Gen 2)
-Best glitches
Gen 2:
-Only real postgame across every Pokemon game
-Best lore, simple, clear, and you had to look just a little to find it
Gen 3 (My least favorite, bear with me):
-Did this gen actually have anything completely unique about it? Maybe that's why I hate it more with each new gen.
-Multiple evil teams at war with each other? I dunno, it had the worst evil teams and worst legendary story.
Gen 4:
-Underground (Could be utilized better now, though.)
-Poketch, we haven't had as good a feature since
Gen 5:
-Entralink, definitely
-Most sympathetic villain/antihero (Also antihero done right, sympathetic but misguided character rather than LOLEDGY)
Gen 6:
-PSS (Not going to be exclusive soon, I'm thinking)
-Super Training (the window is more useful than the actual training...)
