The next version of SimCity will include global warming, brought in in collaboration with oil company BP. Players will be able to choose how to power their cities; if they choose cheap, dirty, carbon-intensive forms of energy, their carbon ratings will rise, and eventually bring about natural disasters. However, players can avoid that by using various BP Alternative Energy-branded low-carbon power options. Nice bit of greenwash there.
Rumour has it that the subsequent version of SimCity will tackle the obesity crisis, by causing your city's obesity levels to rise and health costs to spiral unless you build McDonalds Healthy Eating™ restaurants.
