The World: Environmental Storytelling and Systems
One of the biggest mistakes a designer can make is treating the game world as a static movie set. A living world communicates its history without relying on text logs. Instead of forcing the player to pause the game and read a journal entry about a historical war, the player should feel that history by walking through the craters and rusted swords left behind. According to Hemmann’s analysis of Elden Ring, the landscape itself functions as a storytelling device, using the rot and stagnation of the Caelid region to narrate a story of ecological collapse and the failure of stewardship.1 This is what separates video games from books or movies! The environment does the heavy lifting for the narrative, allowing the player to discover the lore organically.
However, a beautiful visual backdrop is only half the equation. An immersive world also requires robust underlying systems. A landscape that looks alive but does not react to the player will quickly feel like a theme park ride. This brings us back to the MDA framework. To achieve the aesthetic feeling of a breathing ecosystem, developers must engineer the invisible mechanical rules to support it.2 When designing a living ecology, developers must write exact code logic, which Raph Koster explains was necessary for Ultima Online to handle concepts like producing resources, eating grass, or desiring gold.3 If a digital wolf hunts a digital deer, it should not be a scripted animation, but a dynamic system resolving mathematical resource needs.
But introducing this level of simulation introduces a massive risk. Players are agents of chaos, and they will poke at the seams of your simulated reality just to see what happens. When building these environments, designers cannot just code the biology; they must also account for systemic fragility and the chaotic human element of players who will inevitably break those systems.3 If you build a delicate virtual economy, you must expect players to hoard all the gold or burn down the forest. Designing a truly immersive world means anticipating that chaos and ensuring your underlying math can gracefully absorb the impact without the entire game crashing.
