Global Control is a strategy game with a very cynical atmosphere, that uses black humour in order to denounce the shortcomings of our world. It is still in development and will be edited (if all goes along the schedule...) in 2020 with Oka Luda. Although the web page is currently in French only, the game will be translated and available in English when released.
What would Mars and Venus look like with water and clouds? You can see a 3D animation on this page.
