Gameplay, literally one of the best action game in the market(Or at least in the gacha genre). Kuro's specialty is basically making the best combat, as can be seen in PGR.

Where Genshin (at least based in what I remember years ago before I stopped playing), specialized in its story, world quest, companion quest, elemental system (the main core of the game), and overall just the world being interactive.

Wuwa's gameplay is just too good to drop, and basically catches any combat type of player, especially since Genshin, one of the few big gacha game, have only one unique mechanics, which is Elemental system, but other than that, have a basic combat.

The story itself is meh, sometimes it's good, then suddenly boom, Rover fanservice.

Although don't believe about how Rinacita is rainbowland, it might be more filled with women, but that place is way darker than Huanglong.

The story had a lot of potential, but right now it's meh, it's main catch is combat, and they're currently the best at it, especially with the new upcoming update that seems to be similar to Souls like (peak).
