I'd have to say Sinnoh since I love colder climates. I thought long and hard about all the other regions but surprisingly, the longest snow section is in Sinnoh. No other game comes close to the amount of snow and colder whether than in that game. As for what region I would want to see next...I'd want to see several regions where we use the ultra-wormhole to travel to other worlds and experience Pokémon like never before. That would be a really fun game if you could become a traveler through time and space.
I'd love in either Sinnoh or Unova. As much as I love Hoenn and Alola, I wouldn't like to live there due to the warmer climate. I'd prefer somewhere a bit cooler. I guess Johto would be bad place to live either.
I'd want to live in Kalos, since it's based off France and I'd be familiar with it. Also, scarves are super trendy in France.
I would like to live in Johto or Unova region. Johto has some pretty cool cities like Ecruteak city and Voilet city and Unova is beautiful and have lots of variations in itself.
I'd want to live in Sinnoh or Unova. Unova has big cities and I really love visiting the big city, and you can learn a lot from Sinnoh while being in a cooler climate, which sits well with me since I generally dislike hotter days.
It's between Sinnoh or Hoenn for me. Sinnoh is my fav, and it has both warm and cold places, so I have some choice. Hoenn would be nice because it's really colorful.
Sinnoooooooooh It has an amazing range of environments, a lot of dope Pokémon, and lore and mystery galore. It has all I want.
