It's a fun game, that is until you reach the end game. Starting the game for the first time felt so magical and new. There's a lot of areas to explore, get chests, do puzzles and such. Unfortunately, once you sweep the whole land of these said chests and puzzles, there would be almost nothing left to do. As an end game player, I usually just spend 30 minutes or less per day in playing genshin. I would log on, do my commissions, spend my resin, and then log out. If you want more challenge, I guess you can sweat in the abyss which is the game's only end game content.
Another thing to mention is the game's gacha system, not with the characters but with the artifacts. Artifacts are basically the vital parts of your characters, and doing domains for months just to get the right stats and sub-stats for your characters are starting to get unhealthy and not fun at all. Don't get me wrong though, I find genshin very fun and cool, but it doesn't mean it's the perfect game. If the developers were to add more end game content for the players (aside from events), then the game would definitely become less of a task and more of something you would really enjoy playing.
