This War of Mine is quite a neat game which although based around war can also share similarities with a zombie apocalypse. I think any game which tests people's morality is good preparation.
For example.
Do you steal from an old couple hiding out in their home leaving them with nothing and possibly starvation just because they are old and you have many more years ahead of you? How does one rationalize one's own existence in these circumstances. Is there a right and wrong and who decides when the world around you has gone to pot where previous rules no longer apply. If you're in a group some might appreciate the resourcefulness of gaining food but others might take a difference stance and chastise for your actions.
