Ensemble Studios worked together with Big Huge Games to develop "The Asian Dynasties", "Age of Empires III"s second expansion. This was the first joint venture for both teams. The reason for them doing so was compatible schedules: Ensemble Studios was busy with other projects—particularly "Halo Wars"—while Big Huge Games' real-time strategy team had few projects at that time. Big Huge Games did most of the work, but Ensemble Studios designers Greg Street and Sandy Petersen joined in the brainstorming, and had control over the final product. Both studios had roles in testing the game before its release.
