GDN writes: "Software development is often least painful when you start with a simple base case and then carefully add discreet layers of complexity to it. Wolfire has been following this principle for the production of its new game Overgrowth by focusing on terrain first. Terrain is the simplest and best starting point because it will interact with and affect every other object in the game. Because players will spend nearly all of their time outdoors in Overgrowth, the terrain will be the most viewed asset in the game. With this in mind we've been putting tremendous thought and effort into Overgrowth's terrain system. This dev diary takes you through the start of our development."
