Ghost of Tsushima is a very fun samurai game, and if that's what you want, then Sucker Punch has you covered. If it's not what you want, then who even knows what to say to you?
Visually breathtaking, mechanically pleasant, Ghost of Tsushima is just supremely enjoyable. It features some open world busywork, but the beautiful setting and delightful mix of stealth and honorable combat make for significantly moreish entertainment.
It's like Assassin's Creed, but significantly better.
