I've never quite understood the people who want t catch old pokemon on their first play through in the new region, I've always focused pretty exclusively on getting new Pokemon. When Sun and Moon came out, I nuzlocked it for myself for my first (and come to think of it, only) playthrough of the game, but made the rule that I'd only do new and alola form pokemon, and ignore all the others. I'm HOPING (fingers crossed) to experience Sword or Shield for the first time as a Nuzlocke let's play with my wife, though, so.. I don't know if I should keep that "only new pokemon" rule in a format like that. On the one hand, it might feel a little bit cheap to me, on the other hand, I WANT to use the new Pokes more than anything else.
