Here are some games that I believe are worthy to take a closer look at.
Although I have been asked "Why link to other games?" For me the
answer is simple, hope... Hope that some of us will be inspired to make changes
in our lives which "will" change the world.
World Games is the beginning of a compilation of resources for and about
games that are attempting to solve World issues, check it outand become part of the project.
Think Progress has a list of many games that are related to Climate Change,
it is also a great source of other related information.
