It's a detailed strategy simulation that place you as head of a fictitious group who have world wide power to crate worldwide and country based policies.

It's a very addictive and mind opening game and certainly shows the difficulty of dealing with Climate Change!

It should be on GOG, but meanwhile I have put links above so you can check it out.

A New Beginning is a great adventure about Climate Change. Fate of the World is a great strategy simulation about dealing with Climate Change!

Thanks for the sharing. Just checking and it looks interesting.
Loved the way of dealing with the climate change in A new beggining. So important nowadays.
