no one is gonna use Popplio.... doesnt look good.
Rowlet & Litten look much better.
U wot m8!? Popplio is cool and silly. And a clown. He's top tier starter. Litten, on the other hand, looks like a barfed cat.
Rowlet is fine.
OT: besides the Pokemon themselves (which I'm sure we will all get used to them later on), it looked pretty good. No more 8-grid movement, gameplay looks like cutscenes from XY/ORAS (so no more chibi looking people), customization is back, and the region looks quite big and interesting. Pretty good.
