It's been a week since USUM launched (longer for some of you). That should've given you plenty of time to finish them. With that being said, its about time that we rate the 3DS Era of the Pokemon main series.
>Tell us what you like and look for the most in a Pokemon game, so that anons understand you point of view better (exploration, characters, difficulty, mini quests, etc)
>Order Pokemon XY, ORAS, SM, USUM from best to worst
>Optional: Explain your reasoning for each if you can.

I'll start.
>In any Pokemon game, I look to learn more about the Pokemon world via exploration. I enjoy finding lore outside of the main story.
>My Rankings: ORAS > USUM > XY > SM
>ORAS, while being easy as shit and no BF, was enjoyable to me because of how it expanded its multiverse lore with the Delta Episode. Plus, I really enjoyed stuff like the Sea Mauvile sidequest.
>USUM was good and I enjoyed some points in the game where I was forced to buy potions and revives for the first time in a while. But I felt like that should've been the case in SM.
>XY introduced Mega Evoultions, something that I enjoyed as it revitalized new mons, and had some fun social activities like Friend Safari that made it memorable.
>SM introduced Z moves and an evolving legend, which was cool. But coming after ORAS made it feel really dry in the post game department. Not to mention that it felt largely incomplete.
