Great survival sandbox game. It's constantly being updated, so each iteration is like a new game, and I've added many more hours with each version. Hard to put down once you get into it. The zombies add a lot to the gameplay but the sandbox element takes it to the next level. Lots of fun with friends working together. Online PVP is exhilarating and very satisfying when you're victorious, but utterly demoralizing when you're defeated. One of the only games I lost sleep over, with fear of being raided. What a rush! No other game has captivated me this way. It's not for everyone though. It takes time and patience to advance into the late game, so those that like ultra fast paced shooters may shy away from it. Players either totally love it or aren't into it. If you like survival games, zombies and sandbox elements, then it's a recommend from me.

It's popular with married couples I know. There are about a dozen couples I know that started playing games together because of 7 Days to Die. Many of these couples had never played games together previously.
