All and all Let's GO is shaping up like standard remake fare. I'm not seeing anything in these games that are going to be shaking up any formulas any time soon. They do drop a good bit of the standard formula (hold items, breeding, abilities), but as far as I can tell that is exclusive to these games. I wouldn't be surprised if Let's GO became its own line of games that run perpendicular to the style of games we are more familiar with. Although, I have no idea who the starters for a Johto style Let's GO game would be. Maybe the Spiky-Eared Pichu and Togepi?
Nevermind, apparently I know exactly who they should be!
