This War of Mine is my favorite game, and I've sunk hundreds of hours into it. The drama is unlike anything I've seen in a video game, and it inspired me to read a few memoirs and books on the war that it is built around. (I highly recommend "The Cellist of Sarajevo" for anyone wanting a book.) My review of the game, written just after I bought it and played the first game, is here http://steamcommunity.com/id/EdenStarGazer/recommended/282070?snr=1_5_9__402
But, one thing I most like about the game is the fact that you get to make choices about how you will play the game ethically. You can choose to operate with a sense of cooperation with other survivors and respect for human life and possessions, or you can choose to survive at any cost. It is entirely up to you, and it is possible to win either way.
They've added on the ability to create custom scenarios in recent updates, and you are now able to add photos of yourself and your friends, for example to custom characters, and you can set up an easy scenario if you choose, to start.
The winner will be added through Steam and gifted the base game. The contest does not include the DLC. The game does have Steam cards & achievements. The achievements can be completed easily in two play-throughs, though you probably won't survive your first war. Good luck!
