Leave it to cows to call it boring and a walking sim but then go and brag about Death Stranding.
Death Stranding has gameplay.
There's still more walking in that game than there is in The Medium. You go and see a walkthrough and all you will see is walking through terrain majority of the time.
I don't have a pony in this race, but it's basically impossible to have more walking than there is in the Medium.
Which is fine - it's supposed to be that way. But your argument makes no sense.
