Rejoice! Now you can become the CEO of a multinational evil energy empire on your home PC. Build as many nuclear power plants as you always wished, destroy the world’s climate with coal electrification and make a big advertisement campaign to greenwash your evil plans with some wind-mills 😉
You can download this great looking game called Energy Tycoon, for Windows and Linux, and the source-code is available under a MIT/BSD like license. It includes some non-free parts however (e.g. irrklang AFAIK) and the media license is unclear, but it’s rare that such a polished game shows up as open-source more or less out of nowhere.
