All in all, I would say Honkai Impact 3rd is an action-packed RPG game like Genshin Impact, and you should try it out right away. Recently, the developer added many unique characters and armor, so that is great for players. As a result, you will be able to obtain powerful weapons called Stigmata, just like the Elemental powers you have in Genshin Impact. The more victories you have, the more in-game resources you will earn. You can get new weapons by either crafting or through the Gacha system. You can switch between characters and fulfill the team roles with various weapons and equipment. Each Valkyrie has unique skills and attacking capabilities.
The game revolves around three unique characters, known as Valkyries. It is an intense RPG game in a fantasyland, and it also offers a Gacha system where you can get weapons, outfits and transform yourself into powerful characters. If you are looking for the best game like Genshin Impact, then Honkai Impact 3rd would be my top recommendation.
