Hell yeah, man! I could bring up a totally revamped Malik Grizz, or even do a new character. My SU skills are so much better than they once were. And that swag cruise ship was pretty awesome, I thought. But at least we'll have SOME portion of the old crew. You know. For nostalgia. We won't have Pat, Zapdos, or anyone that I actually interacted with, although I do think I interacted with Doge once.
I think it'll be pretty great having gen 6 Pokemon in there, in case you haven't already considered it. I don't really have much in terms of suggestions, but if you want my opinion on something, I'm all ears.
