Graphics, music and storyline are good enough to satisfy , gameplay can be a bit laggy for me but otherwise it's good. The only thing is the rewards. Not quite generous like HRS and HI3. I think a lot of players agree that the anniversary rewards were quite disappointing. And how smooth your gameplay is really depends on the device (in my experience at least). Out of all solid game. (nah not really :3)
Came back after 3 yrs of playing and I must say the rewards are.... Very uhm did not change too much! The 3 intertwined fates are uhm very generous thank you genshin! Can't wait for the very generous rewards at the 4th anniversary! (I hate and love this game thanks very much genshin! And please give better rewards at the 4th anniversary)
Side note. I saw wuthering waves and holy moly the gacha system, gameplay and graphics and design look awesome! Might try that instead of ZZZ (Zenless zone zero I think it's called?) quick question, is wuthering wave's storyline good? (if anyone sees it of course)
