zargon the great

Hi i have tried the demo and like EOS. After years of playing the civs, gal civ 2 etc its nice to see a scaled down game. But.. what is the deal with diplomacy with the AI? as in there seems to be vey little. Declare war and that is it, i cant see any way to make peace etc? unless im doing something wrong??? the manual tells you nothing and this is the only forum i can find for the game. Some advise would be appreicated. btw i gather the full game has an amundance of online players? as the demo seems to have none what so ever.
