About Half-Earth Socialism

✦ AI summary

Half-Earth Socialism puts you in charge of global planning from 2023 onward, where you decide which projects to pursue, how to produce energy and food, and navigate competing political factions in parliament while managing climate and human welfare through realistic simulation models. The game challenges you to balance radical transformation against practical constraints, showing how your decisions ripple across the world through climate impacts and societal changes based on the HECTOR climate model and economic systems.

SET THE PLANETARY PLAN: Half-Earth Socialism allows anyone to try their hand as a global planner of a future society. Starting in the year 2023, you must make decisions about what projects the world will pursue--new research like alternative energy sources, or massive infrastructure projects like mass electrification or space travel, or one of over one hundred other possibilities. Decide how energy and food is produced across the world. Should we immediately halt all fossil fuel usage, or should we swap to a "transition" fuel source first?

WORK WITH PARLIAMENT: At the same time you must juggle relationships with competing political factions in global parliament and improve the quality of life for everyone on the planet. Will you be able to guide the world into a better future amidst differing interests and visions?

IMPACT THE WORLD: Half-Earth Socialism features a simple model of the world: the impact of your decisions are simulated using the HECTOR climate model and a model of planetary production and demand. See how the world changes according to your actions--perhaps new culinary trends around eating invasive species, or the emergence of eco-terrorists if your plans fail to improve planetary health and human well-being.

It is a very fun game, with well-made underlying mechanics and an overall great message, ruined by the dev's [or book that it's based on?] underlying biases. The TL;DR is that there is basically only one path to "win" the game. The only way to fully solve the meat crisis is to go vegan [reformism in the industry or tech-focused alternatives like lab-grown meat can't fix it], the only way to fully solve the energy crisis is...well actually, I still haven't figured that one out! Even going by the paths that are suggested/alluded to by the book and the dev's beliefs, its still kinda a coin toss to get the most optimal ending. There's like ~10 different factions, but most of them are only there to hinder you. Siding with, and going fully into, the majority of them leads you to either the "loss" state [being kicked out of office], or one of the many "middling" states [usually some kind of "you die wondering what else you could have done"]. For a long time I thought the game just had a pessimistic bent, until I looked into it and found out there *is* a good ending where you retire, but again, you have to go a very specific path/ideology in order to achieve it. Want to try and establish…

Incredibly difficult strategy game, very appealing, hours of gameplay, reconfiguration, and endings.

it's been years and i still come back to this game time to time it's a fun way to spend an hour, and it's beautiful to have visions of a better future

This is a tough game. Usually, you will end up with shortages of food and electricity or you fail in reducing biodiversity loss. I have not won it yet. Most of the time, I end up being hunted by a mob. I am yet to work out how to reduce food shortages. Still, it is a good game and works at explaining the ideas of eco-socialism.
