Largest playable videogame galaxy (accurate)

Elite: Dangerous (2014) uses its own bespoke system, named Stellar Forge, to procedurally simulate a playable solar system that replicates our own solar system with considerable scientific accuracy. As calculated by developer Frontier Developments, Stellar Forge generates 4,918,906,760,000 cubic light years worth of playable area for players to explore. That equates to 4.1,652,646,488,954 x 10^60 cubic metres in actual size.

Although rival space simulation No Man’s Sky may theoretically procedurally generate a larger playable galaxy, Elite: Dangerous simulates a “real-world” galaxy based on scientific discovery and knowledge. “Every object from our solar system is the right size to its real-life counterpart and every distance is the right size,” Frontier Developments explained to GWR. “That means our solar system alone is billions of times larger than the largest open-world game you’ve ever played.” By way of further example, the simulated Milky Way in Elite: Dangerous also contains more than 150,000 named objects, all positioned correctly in the night sky.
