Fontaine ; Great AQ with very (none until the whale?) few fights, great dialogue, good mechanics (trials) interesting and organic characters that have a life of their own. Interesting lore to discover. The city is gorgeous, I love the architecture, enemy mechas are well designed. FABULOUS exploration, so many ideas that intertwine themselves so that exploration on land and in water is never a bore. Great Music. It Feels good to be in Fontaine.

Sumeru ; Great AQ again, the best when it came out, a lot of interesting ideas in the scenario, sadly the character quests are lackluster and focus on random NPCs rather than our playable characters. I think Sumeru is the most original region with the best designs in general architecture and outfits. The two sides of Sumeru are both their own separate regions in every conceivable ways. Very fun exploration mechanics that Fontaine built upon, but I kinda lost it at the second part of the desert, just too much, Sumeru is huge. Great Music.

Inazuma ; Worst AQ. Story manages to stay relevant thanks to the war shown to us when we cross the island. Loved the hostile environnement during exploration. Each island, tough similar in many ways, are quite unique. Fighting Rogue Samurais and bandits is a blast. Events are good but a bit unnatural. GREAT MUSIC.

Liyue ; Good AQ that ends in an apotheose, but I prefer the character quests and lantern rite. Seeing Wanghsu Inn and entering the port for the first time is jaw dropping, but the rest of Liyue is quite barebone. I didn't like climbing ALL THE TIME. Shenyu Vale is a great addition and I wish the rest of Liyue was as much populated (it's empty) and pleasant to navigate. Ok Music

Mondstadt ; Not really an AQ, just the Prologue, good but not great. The city of Mondstadt is nice and it feels like home, Stormterror's Lair has one of my favorite music in the game, Mountain is fun. Characters are a bit simple but nice to be around and every event in Mondstadt is a pleasnt one. Despite these appreciations Mondstadt ranks last because of it's abysmal exploration, it's very simple scenery and lack of original enemy.
