This game has climbed the ranks to becoming my favorite game ever, and feels more like the natural evolution of Tenchu: Stealth Assassin, and I mean that in the highest regard.
The combat feels sharp, fair, and lethal.
The exploration feels natural, and nothing feels quite as wonderful as following some random bird to a secret, or a fox to an Anari Shrine.
Progression is wonderful, with many skills to unlock/enhance, and cosmetics to discover scattered about the beautiful open world.
The world is captivating. Simply stunning.
The photo mode is the best photo mode I've ever seen in a game.
The narrative is compelling and the side quests are all given meaning, to some degree.
I could go one and on, but you should get this game, and play it for yourself. You won't be let down.
