地球帝国
Development of the game began in 2005, shortly after "Empire Earth II" was shipped. The game engine was built on Empire Earth II's engine using Gamebryo 2.0 middleware, but was almost completely rewritten to allow the developers to create improved visual effects, ragdoll physics, more detailed models and higher resolution textures. Instead of making the units more realistic, Mad Doc Software worked to achieve a more "cartoonish" look.
