I love the traditional design and overall feel of Ecruteak. From the burned tower, to the theatre wherein Geisha gracefully perform on stage, Ecruteak is a location full of beauty.
The soundtrack for Ecruteak City in the remakes is so beautiful, isn't it? 😍
Kanto: Celadon City – I always loved the upbeat music, the big city, the pleasant Grass-type gym ran by Erika, the shopping mall, the Pokémon Mansion with the Game Freak development staff, and the Game Corner. Another close favorite would be Fuchsia City, mainly because it had the same soundtrack as Celadon City, and the Safari Zone.
Johto: Olivine City – I used to enjoy playing Pokémon Crystal at night just to catch Staryu with my Good Rod along the coast of this port city. Staryu evolves into my all-time favorite Pokémon, Starmie. I also enjoyed the S.S. Aqua rides to Vermillion City. Ecruteak City is also a close second in the remakes simply because of that beautiful soundtrack in the background.
Hoenn: The crazy thing about Hoenn is that, despite me loving this region to death, I don't really have a specific favorite place in these games. I really enjoyed Slateport City and Lilycove City, but in the remakes, my actual favorite place was in the sky when
Soaring in the Sky with Mega Latias via the Eon Flute. I loved that feature so much that I hope it returns in future games. If it counts, I also loved the Secret Base that I created as well.
Sinnoh: The Old Chateau – I love this haunted mansion strictly because of its spookiness and because it has Gastly, a Pokémon that evolves into one of my all-time favorite Pokémon, Gengar. It also contains Rotom, which is a Pokémon that I've grown to like from playing the Alola games. Anything involving Giratina is great as well, including the spooky Reverse World and Turnback Cave. Despite Sinnoh being my least favorite region, I commend Game Freak for putting a lot of effort into many spooky aspects of the game.
Unova: Castelia City – Check my location! I'm born and raised in Castelia City, and got love for Castelia City, so I've
gots to rep for Castelia City! Best location in the entire Pokémon universe, hands down. I never thought I would ever see my hometown remade into a Pokémon game.
Kalos: Lumiose City – It reminds me a lot of Castelia City! It's a big city with so much to do, many places to shop, various Battle Buffets, which are great for training, is the setting for a good post-game storyline, and is easy to get lost if you're not careful!
Alola: Hau'oli City – Hard to choose because I love everything about this region. However, I love Hau'oli City because of the shopping and Battle Buffet. I spent a lot of time training my Pokémon at that Battle Buffet, competing with Queen, and had tons of fun doing it. Other places I enjoyed are Malie City because of its callback to Kanto and Johto, and the Ultra Crater in Ultra Space because I love Celesteela and seeing her take off like a rocket in the background. The Battle Tree was also very fun and fit the Alola look and feel as well.
Galar: – Isle of Armor. I love all the wild areas, but something about Isle of Armor is amazing. It has tons of Pokémon to catch, many different locations, soothing music, and has a nice Alolan feel to it. I also love Wyndon because it's a big city, has my favorite Battle Tower of all Pokémon games, good shops, and is the place where you hyper train your Pokémon. Hilbury is also a great place to be simply because of its soundtrack. I jam to that song every time I hear it.
Hisui: Jubilife Village – I enjoyed this place as fun little hub village when playing Pokémon Legends Arceus.
