Genshin Impact if it was turn based, before finishing the tutorial I knew that the game already showed me almost every mechanic.
As always with this company the worst thing about this game is the gambling mechanic attached to it, the best and most interesting characters are tied to the gacha and if you are an unlucky person you are fucked. The best equipment is also tied to the gacha, the upgrades that are noticeable are also tied to the gacha, even if the game is very easy this is still a problem as the best way to be powerful it's not by playing but paying. The characters have 1 basic attack that it works almost always the same for every character, a special ability, a passive and an ultimate, and they don't combo in fancy or interesting ways, they do their own thing and that's it. Having this problem with how small your options when fighting are, the game really starts to feel to samey at the beggining, and as you know that the character will never learn a new skill, ability or similar it feels even worse, if the game is gonna be so slacking with the character drops then every character should have like 5 or 6 abilities at minimum.
The enemy variety it's also not the biggest forte of the game, taking me almost to just before you fight the important boss to find a new one, but before that you are fighting the same enemies for like 8 hours.
The game also picks the worst parts of Genshin an borrows them like they are good things like the artifact system, the Energy (Resin I believe it's called) system, daily quest that no one likes, locking the progress behing a account level system, etc.

I will not talk about the story as I skipped it as I finded it uninteresting by the end of the tutorial, maybe it's good later who knows, but I have to complain that I can't skip it if I don't find it interesting, so far Mihoyo is one of the few companies that does that.

And even if I didn't reach it I can say for sure that the endgame will be log in, do the daily quests, empty energy, exit, with a little of weekly progress.

Oh and BTW Taiwan it's a forbidden word in the game, just saying!.

While the game can be great at some times, it can be pretty horrible at others, my biggest compain is how annoying the stamps at mementos are, and the lack of an endgame zone that is out the game, maybe a bigger arena aside from the challenges at the velvet room would be cool.
Also the pacing in the dungeons could be faster it gets old very fast when every door is "JOKER THE DOOR IS LOCKED", then the game zooms out for the way were is the lever for the door, you go to open the door and then they say "MAYBE THE DOOR IT'S OPENED????", you go to the door and they say "YO JOKER THE DOOR OPENED WE CAN KICK THIS ASSHOLE ASS, YOU ARE SO SMART". It slows the game so much maybe you could cut 20 hours only removing that.

The boss of the base game was annoying not hard, I was underleveled and took me an hour to beat by how bloated his HP was, also there is the boss of the factory that god knows by has a 30 min timer that has no place in a turn based rpg.

The game also could make even easier to max out all the confidants in one run I would like to hang out with people that I had maxed or go to places like the maid cafe when I maxed my stats just for fun, and in the persona part I would love an option to store the personas, by the end of the game I had a full team and I couldn't fusion without wasting money in killing and ressumoning personas, ah and the fusion system is a nightmare if you want specific personas, and the dlcs are busted at astronomical levels.

Aside from all that, I found the game fun and really cool, not a fan of the story, but the characters are very cool my favorites being the twins hanging out with them was my favourite part of the game, also making the strongest personas was fun too, some desings of the demons are sick like alice and lucifer.
