So I am working on a system of mechanics. I want a game that decenters combat, and that centers biological engineering, social interactions, and plumbing. The setting is solar punk, on a space station. The aesthetic is weeds in the cracks. The setting diverges from our real world in the 90s, when the biosphere 2 experiments were being conducted, in the game world they were successful and biological science advanced enough to make constructed biosphere's in space practical. Africa ended up uniting and an international organization, with the US, Russia, China, the EU and the AU (African union) as members ended up constructing an international space station. Poop is an important resource, controlled by waste management, who are known as the shit lords. hoarding poop is a serious crime, and jenkem is a drug widely considered a scourge on society. Combat, if it occurs at all, is handled with a single roll and some free form roleplay. biosphere modification is a daily task, along with group politics such as propaganda, and crafting, on a more short term time scale there's mostly interpersional interactions, hacking, and plumbing, which includes atmosphere engineering. The rogue plumber in brazil is definitely an inspiration. Biospheres have varying degrees of biodiversity, and once they are diverse enough they start to alter their environment towards their ideal conditions. players can help or hinder that, and they can also work to change the biosphere so that it has different ideal conditions.
