Pros
Pro Realisticly tough decision making
Users must make many choices in game that can result in many realistic consequences. Should the player take a gun out with them to scavenge, what if they run into enemies and didn't bring one? What if they brought the gun but now don't have room in their inventory to collect all the items needed to survive the next day?
Pro Creates a sense of fear
Through using the use of sound/graphics as well as how pertinent it is to find supplies, going out into the world where almost all interactions are fraught with danger give a real sense of fear as to not get killed by the worlds survivors. Every sound or shadow moving makes for a world that should worry the player and then some.
Cons
Con It's incredibly depressing
The story is a sad one, the outcome of your decisions will often be the result of two bad options with one being slightly less dark. War is terrible, and this game never lets you forget that. This is amazing, and true, but can be difficult for those who need to find some measure of light when they game.
