i had a dream about this really great idea for a video game
ok so its like this horror game and in it you are a ghost in a small conservative church town and each level is a different day of the week
basically the point of the game is to mess shit up and disturb as many people as possible before your life energy runs out
things that deplete your life energy include passing through solid objects, killing people, using special abilities, and using physical items such as spraypaint or crowbars.
the more shit you ruin, the more people are going to pour out of the buildings. the more people there are, the more likely one of them is going to wise up to your antics and stop you in some way. these are the people you need to kill, and you want to kill them in the most graphic way possible. if you fail to do so, they will call attention to you and a local priest will exorcise you.
every one of your destructive actions give you a different number of mayhem points. smashing a windshield, for example, may score relatively low. setting a priest on fire during a sunday sermon would yield a much higher score.
different days of the week present different scenarios and new opportunities such as the sunday sermon scenario. at the end of the week, you are either sent to heaven or hell. the goal is to go to heaven, but you can only do so by causing the maximum amount of chaos and killing as many people as you can along the way.
