I was thinking more along the lines of a logans run. We are cast out because we are too old or for picked in a lottery. Rather then kill us, we are sent past the safe haven. They drop off weapons and supplies in hoping that we will thin the hordes. But there are others that have survived the hordes like the dukes and white rivers. Maybe the dukes are planning on attacking and raiding the safe haven as a plot. We can join him or stop him for a story.That would be an awesome way to start the game. That way you could start with some basic resources. And a better starting quest.
Either that or be tied up in the trunk of a car captured by some cannibal driving you to his dinner party. You jump break free and jump out of the trunk. Following a set of clues to find him hunt him down and kill him.
Super easy basic storyline but it would give the game a purpose.
Feel free to pm me for a whole storyline.I have a whole thing fabbed up in my mind.
