I never use the Grass starter, so I'm really looking forward to Chespin. Apart from a few pieces of fanart, I have absolutely no idea what his final evolution will look like, so I really hope its good.
I dont have to choose just one starter, thats the great part. Having friends that you trade the starts to then back to you for the win. Makes you spend an hour or two before you can really embark on the game, but its totally worth it when you have all 3 starters around level 11-14 with you. No picking ftw
