Is Death Stranding worth it for 22 quid?

I enjoyed it. It certainly is very unique and the mood is special. The gameplay is a little misrepresented: yes, it's mostly walking, but it's also the first game where I was like "there's a lot of stones down there, I take a different route", which connects me to the world.

I've never seen a game where terrain was more than just rich texture, this one is it. Kojima game though, so expect long cutscenes and people hammering points home that you already understood.

Would you say it's relaxing? I tend to like pretty games which I can dip in and out of.

Well, it has horror elements, but when you are outside of them, it actually is. It has tons of enjoyable scenery to explore. It has this "look to the horizon, pick a place and then walk there" that hiking has.
