John, I developed a game using the Sierra Engine in the early 2000s, a modded version of Empire Earth. It became popular enough for others to host it on their servers. The game featured 3v3 matches, where each player controlled around 150 units. These units would upgrade and respawn as players accumulated more kills. Having someone appreciate your work and your games is one of the best feelings I've ever felt.. still chasing that high now under Satoshi Settlers.  
  
Dalia, will respond soon.
