- Space games struggle to depict the realistic scale of the universe due to its vastness, such as the 93 billion light-year observable universe and 100,000 light-year Milky Way.
- Game developers use techniques like level-of-detail scaling, procedural generation, and travel compression (e.g., jump gates, time acceleration) to balance realism with playability.
- In games like X4: Foundations, developers create dense populated areas and empty frontier regions to convey space's emptiness while avoiding boredom during travel.
- Elite Dangerous features a 1:1 scale Milky Way with 400 billion star systems, using Stellar Forge for procedural generation, but only a tiny fraction has been explored.
- Travel in space games involves tiered systems (e.g., Supercruise, Hyperspace) and resource management (fuel, heat) to engage players during long journeys.
- Asteroids in space are typically far apart, making accidental collisions unlikely, contrary to common media portrayals.
- The core challenge is balancing fun gameplay with realism, as simulating true cosmic scales exceeds current hardware and human comprehension.
