Final is a space simulation built on a foundation of scientific realism and neofrontierism. Set in an alternative-reality solar system rendered with 64-bit precision, the game features real orbital mechanics, deterministic construction systems, and a living economy driven by primary industry — from copper mining and refining to transport logistics and commodity markets that fluctuate based on supply, demand, and distance. Everything in the world is driven by deterministic functions: building a bridge, refining ore, or plotting a course between planets all use real calculations, not procedural shortcuts.

At the heart of Final is the Node System — a geospatial framework that runs every complex system in the game. NPCs follow node-driven behavior cycles: working jobs, joining group events, responding to emergencies. Players interact with the same system, creating emergent stories across mining settlements, space stations, and planetary surfaces. The game features full calendars with days of the week, seasons that open and close passages (ice routes, orbital windows like the 2026 and 2028 Mars windows), kiloday birthdays, and events that reshape the world.
