Combat is nice, characters are nice, world exploration is nice. Artifact farming and endgame is unforgiving garbage.
Gacha is fine, for gacha standards. Story is also nice, although really text-heavy.
The reason I dropped Genshin and stopped playing was because I lost all motivation to keep playing after missing too many time-limited events that play a huge part in fleshing out characters or the lore as a whole. No plans of reintroducing such events as replayable content (except for ONE statement in 2022 that lead nowhere). Stay away if you don't like some character being blank canvases due to their character development only appearing within events.
