Shadow Fight 3

Shadow Fight 3 is visually stunning, plays smoothly, and has an interesting gear system, but doesn't have real-time PVP, and progressing in the game takes forever due to a too difficult campaign and chests with long wait-times.

There's a decent amount of grind here too, as you'd expect from a free to play game. The fighting is deathly focused on timing as well. You need to wait for your opponent to make a mistake, then lash out with all you've got.
