Look, I'm a big fan of Genshin Impact. With that said, I'm not a gacha addict at all. I completed Genshin Impact 99.99%. So this review is mainly aimed at Genshin players.
ZZZ is very similar to Genshin. What it lacks is an open world, a variety of quests and interesting characters. I'm writing this review having reached level 30 in ZZZ and my Genshin account is level 60.
The quests in ZZZ are mostly focused on clearing dungeons, there were some unexpected twists, but it wasn't enough to keep me going.
It's possible (I really hope so) that after some time the game will become very polished, but right now that's far from the case.
My biggest problem with ZZZ is that it doesn't allow me to just wander around without constantly thinking about clearing some dungeon. The game put too much pressure on me for me to fully enjoy it.
Additionally, one of the best and worst aspects of the game is the fact that the resources in ZZZ are almost the same as in Genshin. While this helped me quickly figure out what was what, it robbed me of the satisfaction of figuring it out myself.
Also in Genshin - when you pull out a weapon, you can see when your character is using it - and in ZZZ I couldn't even see the weapon attached during the fight.
Combat in ZZZ seemed much simpler than in Genshin. I may not have realized the depth of the combat yet, but most of the time I was just mashing the strike button. Of course, there are times when you make the perfect dodge or the perfect pass, but if you really want to enjoy this type of combat, just play Sekiro.
My verdict:
1) The game is essentially a futuristic version of Genshin WITHOUT an open world, various quests and interesting characters.
