LGPE players, have or will you complete the Pokédex? If you're currently working on it, how far along are you?
All I'm missing is Melmetal, which I'm about halfway to getting, so the answer is yes, I will complete the Pokédex.
I've completed what's needed to get the shiny charm, plus I was lucky and someone was willing to touch trade me Mew. I don't intend to get Meltan or Melmetal unless someone is offering them as they were not needed to get the shiny charm.
I think I’ll skip on completing the Pokédex in Let’s Go. The shiny charm isn’t an item I’m a big fan of, and with Pokémon Go it’s just too easy.
Done! Excluding Mew, Meltan, and Melmetal, anyway. But I wasn't about to buy into Nintendo's disgusting paywall for Mew, and I don't have a smartphone for Pokémon Go-related shenanigans...at least, not yet. But I've done as much as I can and I am OK with it.
