The Game of my dreams would be a dark humor management game.
It is about running a graveyard, you have to take care of the graves and the income during the day and take care of the dead (that they stay dead) during the night.
To get more "Clients", you can hire the local hitters to get you more people. To earn more money, you can build Hot Dog Stands, a restaurant, sell flowers or create a amusement park on top of the graveyard... the only barrier is your own imagination.
(Who would not like to visit a haunted house at your local graveyard?)
