What I think is the game is good that the only limit is itself.

It has good gameplay, graphic, design, soundtracks and ambition of the dev but I got bored after 2 hours because move sets of enemies are not challenging enough for me.

The limit I metioned is because it's a mobile game so it has energy system and gacha system. I have no problem with gacha games but Genshin just doesn't have enough contents that keep me hook. Also, Genshin still need more end game contents, I don't want to count spiral abyss but that would be the only "end game" content for now.

For me, Genshin(and all gacha games I still play) is not my main game so I can drop it anytime until something interest me to come back.
