OK, so I tried this, able to win on the second round. :-)
First time you risk to do some things too early, others you must do early, but I won't spoil the challenge by giving details.
Good emphasis on land-use limitations.

Concept is nicer than 'fate of the world' which was rather similar (and even fotw told me their idea was partly inspired by an idea on my website about 23 years ago). Both this and fotw based on 'cards', while prefer to adjust levers gradually, and see graphs move in real-time.
(btw going back even further, does anybody remember 'lincity' )?

Some things confusing - e.g. you adjust percentages not totals, but totals change, which hits limits in not-obvious ways. No mention of space-heating challenge eg heat-pumps (suggests made in tropics?), no modal-shift in transport (except inside cities). I'd like to see whether the numbers reflect current emissions of China, and Arabia (I doubt it, doesn't fit the 'south is good' narrative). Overall I suspect that the calculations are too optimistic, but can't say more without detailed plots of changes over time, or a view of the engine code.

But biggest unrealities:

• We don't have such a scenario - there is no global planner - "god games" are too easy concept.
• The fraction of contrarians is larger (than the 3 groups I couldn't satisfy in this game), maybe increasing (?).
• Some of the 'mandates' are far too easily implemented.

I ponder how to design a game which is more realistic in these respects.
Having said that, I think the 'magic card' has some merits, if everybody would play, maybe that helps tip the balance.
