The battle mechanics and animation are awesome and smooth unlike many other RPG games. Though, playable characters are locked behind Gacha system. Playing this game overall is very satisfying and great experience.
However, this game is still lack of content and too repetitive as of now. But, there are some challenges to the game which keep me interested which reset every two weeks.
Genshin also has committed to deliver new contents and updates every 6 weeks. This may or may not worth the waiting time but it still something to look forward.
