Terraforming
Players reshape the physical terrain itself — digging, filling, flattening, raising land — rather than only placing objects atop a fixed landscape. Minecraft's fully destructible and buildable voxel world and Terraria's tunnel-and-build terrain manipulation both make the ground itself a raw material the player sculpts. Designers use terraforming to give players maximal creative freedom over their environment, to enable functional landscape changes (digging moats, flattening building sites, tunneling for resources), and to make the world feel like clay rather than scenery. Key decisions: granularity (voxel/block-based versus smoother, more continuous deformation), performance cost of persistent world changes at scale, tool requirements and speed for terraforming actions, and how terrain changes propagate (does removing ground cause structures above to collapse, as with gravity-affected blocks?). Pitfall: terraforming systems that are technically possible but too slow or tedious to use at any meaningful scale (moving thousands of blocks by hand) push players toward exploits or third-party tools — bulk-editing tools or vehicles become necessary once terraforming ambitions grow beyond a small plot.
