Survival! You start with a core group of players and minimal resources. You build things you need and fortify your house during the day. You scavenge for supplies and food at night. Your choices in game affect how your characters feel and react with others. They get wounded, sick, and tired. All of which affect your choices of who does what in the game. It is a pretty slick game as Ith states. Easy to play and really gets you engrossed in the world these characters are in by the choices you make for them. A definite thumbs up from me.
