Early games used nature as simple scenery. Later, it became a key part of gameplay. Now, in open-world games, virtual nature is a complex, living system that operates independently of the player, creating a more immersive and realistic experience.
When games introduce players to new environments or creatures, it can spark genuine curiosity and engagement with the real world. After Minecraft added the endangered axolotl, Google searches spiked, and an axolotl sanctuary reported a surge in visitors inspired by the game.
Game artists use scanning (photogrammetry) to create ultra-realistic assets. By taking thousands of photos of a real tree from every angle, they generate a 3D model that is a direct digital copy, effectively making the in-game object a "digital ghost" of a real one.
Game engines and procedural generation, built for entertainment, now create interactive, simulated models of cities and ecosystems. These "digital twins" allow urban planners and scientists to test scenarios like climate change impacts before implementing real-world solutions.
Instead of manually designing every detail, games like Minecraft use algorithms (procedural generation) to build vast worlds. This technique, similar to natural laws, allows for emergent complexity and unique landscapes that can surprise even the game's creators, fostering a sense of discovery.
Achieving photorealistic virtual nature requires immense computational power, leading to significant energy consumption and carbon emissions. The gaming industry's emissions are estimated to be around 50 million tons of CO2 annually, comparable to a country like Sweden, ironically harming the real environment it seeks to simulate.
The podcast highlights how individuals with health conditions preventing them from going outdoors, like severe allergies, use games like Minecraft to experience nature. These virtual environments become a vital substitute, offering the freedom to explore diverse biomes and connect with a feeling they can no longer access physically.
