This War of Mine
Video games have put you into war before, but This War of Mine turns the concept on its head by giving you control of a group of civilian survivors. Ensconced in a makeshift shelter in the midst of a war-torn city, you'll have to send your survivors out under the cover of darkness to gather supplies, medicine, and other necessities. They'll encounter NPC survivors that you can either trade with, or take out. You'll have to maintain the health, hunger, and mood levels of your survivors until a cease fire is declared. The time until this happens is random, so you never know when it might happen. It's a different take on the genre, but it's definitely worth checking out.
