I love cooperative games, love engine-building games like Terraforming Mars, and know climate change is one of the biggest challenges facing us today, so this game was a definite yes for me. But, it seems really hard to find good games that cater to more than four players (at least, ones that don't take an entire day to play!) When we get people together to play games, we often end up with more than four people. Any chance that this might one day have a six-player expansion? (Or more?) There are certainly enough countries in the world, so it would be a matter of tuning the game engine to work with more players. I realise that this might mean a revised version of the main game board, but that's a fairly standard thing to include in expansions for games anyway. An expansion to provide for more players would be something I'd get behind.
