https://play.half.earth/ – simple little web game with good communist propaganda, full of fun little references to socialist history and theory.

Here's how to win the game in three turns.

Round 1

Change energy production: Coal, gas, and petrol to 0%. Solar to 40%. Wind to 35%. (I expect any mix of solar and wind would be fine; this one is verified.)

Change energy production: Coal, gas, and petrol to 0%. Blue hydrogen to 85%

Change crop production: Industrial farming to 0%, organic farming to 70%

Change meat production: Industrial farming to 0%, organic farming to 100%

Research: Green ships: 15 years to go.

Infrastructure: Cloud brightening 10 years to go. Direct Air Capture 15 years to go. Electric Cars 16 years to go. Energy Conservation Campaign 20 years to go. Expand Nature Preserves 16. Public Transit 17 years to go. Indigenous sovereignity 3 years to go. Remediate and protect ecosystems 20 years to go. Wooden Skyscrapers 15 years to go.

Policy: Accelerationist, Animal lib, Champagne, Consumerist, Factory farm reform, Marine protecc.

The win-condition is temperature rise below 1° + biodiversity pressure below 20 + emissions below 0. Cloud brightening wins the first directly by geoengineering. Most of the 'policies' are to win political capital for Round 2; this list wins +75 political capital. Most of the research/infrastructure is to reduce emissions by reducing fuel demand; some is to reduce biodiversity pressure.

Round 2

Policy: Ban hi sea fishing. Ecofem. Restrict air travel.

Research: Electric-Arc furnaces 10 years to go. Apex pred: 10 years to go.

Infrastructure: Biochar 15 years to go. Cloud brightening 4 years to go. Wetland protection 10 years to go. Recycling 10 years to go. Pedestrian and bike-friendly cities 15 years to go. Sewage plants 10 years to go.

That wins +405 capital, mostly by the delayed impact of the 'Change Production' work in Round 1. Now you have a free hand.

Round 3

Research: Green ships 4 years to go. Hempcrete 1 years to go. Electric-Arc furnaces 4 years to go.

Infrastructure: Biochar4 years to go. Pedestrian and bike-friendly cities: 4 years to go. Compost: 4 years to go. Direct Air Capture: 4 years to go. Electric Cars: 4 years to go. Energy Conservation Campaign: 5 years to go. Public Transit: 5 years to go. Phase out commercial fishing: 4 years to go. Recycling: 4 years to go. Sewage plants: 4 years to go. Remediate and protect ecosystems: 4 years to go. SRM: 4 years to go. Wooden Skyscrapers: 4 years to go.

Policies: Vegan, detox, no cats, no cars, crypto ban, hunting ban, exotic animal ban

Strategy is to ignore everything that'll take you longer than 13 years. Ignore resource shortages. Ignore contentment. Switching to renewables wins you mad political capital in between rounds 2 and 3; in round 1 you win enough capital to tide you over. You pour all that political capital into the game's three win conditions, rather than all the fun little side things like fanonism.
