The gameplay is actually pretty cool. Especially the sand surfing. It just looks fun.
The game is a bit of a sleeper and likely went under most people's radar. But it's actually solid. The story is good but a little bit simple. You can honestly piece things together before anything major happens. So I doubt if you'd be too surprised there.
But don't let that stop you.
The combat and exploration is where it shines. The combat offers a ton of fluidity and options as you discover or find different abilities (active and passive) that can have a subtle or dynamic impact on your combat style.
The exploration is pretty solid also. It's a decent size open world with tons to see and you'll be exploring a lot to uncover things like armor, or power ups. Even hidden areas for optional bosses or objectives.
All in all, it isn't a bad game at all. And it'll keep you busy for a bit. You can expect a solid 30 hours of gameplay. More if you're trying to platinum the game.
