an environmental serious game, designed to give players an understanding of the science behind climate change, as well as the options available to policy makers and the difficulties in their implementation. The Climate Change Game The Climate Change Game is played by one or two people (sharing the Mouse). Each player is the leader of a country, hoping to be re-elected while trying to cope with the effects of climate change and, hopefully, reverse it. Players make Decisions to change the energy sources their countries use or use them in a different way. Players also answer Questions on Climate Change and respond to Natural Events (such as volcanic eruptions) which affect Climate, People's Choices (unpredictable, popular human actions which impact Greenhouse Gas emissions and tax revenues), and economic or political decisions by other countries that affect the level of greenhouse gas emissions. Players win “The Climate Change Game” – and are re-elected - if they can help reduce global Greenhouse Gas emissions to the level required by the Kyoto Protocol, and are not spending more money than people pay in taxes, and maintain Voter Support of at least 51 percent, and Earth's Temperature is “comfortable" for life. V GAS V GAS is a 3D serious game in which players explore and live in a house that is built to mirror their own. Players begin the game by building a profile including variables such as water use and transportation behaviors, heating and cooling practices, food purchases, and electrical appliance usage. Once the profile has been built, the player can begin the simulation which introduces different scenarios ranging from heat waves to mad cow disease. The player adjusts their lifestyle according to how they would react to these events in real life. All the while, the players' decisions are being measured and recorded, and their overall contribution to N2O, , and CH4 to the atmosphere is measured. Keep Cool Keep Cool is a board game created by Klaus Eisenack and Gerhard Petschel-Held of the Potsdam Institute for Climate Impact Research and published by the German company Spieltrieb in November 2004. The game can be classified as both a serious game and a global warming game. In Keep Cool, up to six players representing the world's countries compete to balance their own economic interests and the world's climate in a game of negotiation.
