A new indie game entitled A Good Snowman Is Hard to Build , has decided on a really strange pricing scheme. Basically, you can choose to either pay twelve dollars for the game, or you can pay a price that is set based on the temperature.
The company will record the temperature each day at 5PM in London in Celsius. That temperature will be the price of the game. That means, on days where the temperature is freezing or below, the game will actually be free!
Of course, winter is ending and freezing days are becoming fewer and far between. But if you look out, you can probably save a couple dollars on the game here or there.
