Was playing some sort of
megagame at school. I was the leader of a tiny African country, Sierra Leone. My teammates were two girls, our trader and somebody else with no specific function. All teams were given paper and some tools to make oil barrels (paper cylinders of specific dimensions). Also some starting money. Siera Leone being a shithole, we got lots of paper, tape and a protractor (and no starting money), so we were unable to do much at all.
So I started asking around and quickly became friends with the other African countries. Before long, we had a makeshift alliance and after some trading was done, other countries started production while we still didn't have shit. Anyway, after a while we too got to start production by trading some of our paper (=raw oil i guess?) to another country (new zealand, which was in the Africa area for some strange reason) for some basic tools. (Because pencils were so rare, everybody was using scissors to draw lines in the paper)
I quickly figured out that selling our oil by ourselves would yield very little profit due to our disadvantageous market position, so I walked up to every single leader in Africa and told them that we should all approach a big country (with access to better prices) and sell our oil to them, keeping us free of pollution (important because no african country had enough wealth to invest in polluting less) and yielding more profit per barrel. This actually worked and I had apparently started the trade with Africa. However, not long after pollution caused one of our best allies (Toga) to be struck by drought, losing basically all their money. I was quick to donate fifty fictional global monetary units (which is a pittance but we only had 400) just bc these people were our bros.
In the next meeting of the NWO, the issue of global warming was brought up and America was to either invest in being more ecological or pay a fine, which seems rather silly in retrospect. (since we had no way to pay the fine and even if we did, the fine amount was the same as the amount they would have to invest...) Russia was also brought up as problematic, but unlike America was actually present at the NWO and agreed to invest. However, America promptly stepped up and became pretty ecological while Russia continued slacking off.
It is at this point that my best friend became the leader of China, and we promptly started forging plans to embargo Russia
and take over the world, garnering support in our own continents and amongst states such as America. At the next Not The UN meeting, nothing happened except bickering and then it ended. Somewhat disappointed in these results, me and my best friend started organising an unofficial embargo against Russia, first finding support in our own continents before venturing towards America and Europe, where we were repeatedly told to go back to our own continents by teachers (whom we just ignored).
We were able to convince all but two countries (excepting Russia) to embargo Russia, before a massive setback happened: Poland (lead by some dude who was way too into the idea of carbon emission rights) had fused with Russia to form the Soviet Union... for some reason? This was not the biggest setback, however. Thanks to Russia's uncontrolled emissions, we had reached the "magical limit" and 75% of all countries promptly had their wealth halved, and the game ended. Having come so close to saving the world through the power of politick and diplomacy, we had failed.
Sierra Leone managed to reach 510 wealth, though, which was pretty nice. I was a bit too busy politicking to pay much attention to what our trader was doing, however.
