I feel like now I've played a bit, I can go through the motions and make my character secure within a week i.e survive the helicopter event, find a car, secure a base, have ample food, water and guns.

For me, the zombies don't really pose a threat any more knowing that I can just make a racket, round them up and pied Piper the fuckers to the nearest forest. I guess I'm waiting for NPCs to really stir things up but that doesn't seem to be in the near future.

What have you guys done to make the game more difficult or entertaining after you got the gameplay loop down?
