Absolutely! Each region has its reputation system and allows players to receive rewards as they level up their reputation in the city. You can obtain lucrative bonuses as you level up your reputation and will enable you to get blueprints to forge gadgets. As you reach the last level, you can receive a region-specific wind-glider and add it to your collection. There are forging blueprints for unique devices that you can get and learn to craft those gadgets. Additionally, you can also obtain new recipes that will help you cook brand new dishes and consume them while you are exploring the world. When the reputation system was launched, I prioritized it the most. I started to level up my reputation as soon as possible. In a few weeks, I was able to max out one region's reputation, and then I shifted to another one. I love the reputation system because you have bounties and requests that will grant you Mora for various purposes. Your progression in the world quests can also contribute to leveling up your reputation. So, it's indeed a good system that Hoyoverse has put in for the players, and I'd recommend you to start doing it once it's unlocked for you.
