I stopped playing Genshin a few months ago but I think some people are a bit too harsh on the game. The honeymoon period of this game is by far the best of any gacha game out there and I daresay is better than most other open world RPGs with its great visuals, exploration and genuinely interesting elemental combat system. The honeymoon period lasts until about AR 30 as well which is a good 50 hours or so of playtime, that is also completely free as long as you exercise even a modicum of self control and don't buy anything. I'd say Genshin Impact is worth at least trying out for that reason alone.

That said, the post-honeymoon grind is absolutely soul destroying and worse than most other gacha games. At least in other gacha games you can autobattle through the grinding but Genshin wants you to do the same boring domain fights over and over and over again for a miniscule chance of getting a single good artifact drop, which is just the tip of the iceberg of all of the effort that goes into making a good character build. It's just too much for me to care about. Most of the events are mediocre to outright bad as well.
