I enjoyed my time with "Rations, Please", trying to do my best to ensure that everyone who could would live.
Tragically that meant 'put together a shoot-on-sight list for anyone who steals a ration' and 'the unemployed and elderly get stiffed'. After a while, I was down to only feeding the soldiers and the farmers. Then all the soldiers were killed and I gave up.
I recommend developing this concept further into a more complete game, as it's quite excellent at getting its theme across.
