We've seen a fair smattering of weird payment models sweeping across gaming these past few years, but this one looks like a first.
The price for A Good Snowman Is Hard To Build is set according to the weather.
Specifically, the daily price is set according to the temperature in London at "teatime," which is around 5pm local time. It is measured in Celsius. The offer lasts during the game's launch period, beginning tomorrow (Wednesday, Feb. 25) through March 10.
A quick Google of London's weather forecast for the next few days shows temperatures of around 8 or 9 degrees Celsius (that's in the high 40s in Fahrenheit), which means the game will cost you $8 or $9. Its usual price is $12. But beware, it looks like the weekend might be a tad warmer, rising to maybe 10 or 11 degrees.
A Good Snowman Is Hard To Build, by Alan Hazelden and Benjamin Davis, is a puzzle game in which the player maneuvers around a playing area in order to, well, build a snowman.
