It's hard to be objective on this game
OK, objectively, WuWa is a fine game. If it's your very first game I think it's amazing, even. It also have a potential to be the best game in the genre, but right now it's super far from this.
Pros:
Probably the best movement I've ever seen in the genre. Fast climbing is buggy, but when it works it feels really satisfying.
Tons of minigames, like, 10+ of different kinds. Pure gameplay-wise, devs surely know what to do. If you are exploring and doing quests, you will definitely not be just mindlessly fighting the same boring battles.
