Like it? Good.
Now take the Minecraft zombies and make them look more human. Add various creepy textures like blank eyes, fat, gore encrusted bellies, naked eviscerated corpses, and nurses in outfits suitable for a low-budget porn flick. They come at you in degrees varying from your college roomate after a bender to how your girlfriend looked after she found out you don't actually have a sister who lives with you. Interested yet?
You get plunked down in the center of this with a bandage, a bottle of water, and a single torch. By the way, you aren't wearing any shoes, shirt, or pants (and for some reason, if you chose a female character, some oddly chosen underwear for an apocalypse). From this, you are meant to avoid numerous ways of death, including, but not limited to, starvation, dehydration, mauling, stabbing, dysentery, eaten by wild animals, crushed beneath rubble, falling from cliffs, and the always enjoyable slow death of z-virus infection. And that is just during the daytime. By the way, did I mention that when the sun goes down every zombie gets a steroid boost that turns them into beings that would make Olympic sprinters jealous?
7 Days to Die is unforgiving, time-consuming, rage-inducing, and will give you new reasons to fear sunset. You will spend hours upon hours searching for the forge book and even more nights cowering in your makeshift structure while the world goes to hell right outside your door. Should you buy it? The better question is why haven't you bought it yet?
