. . . there are several different ways to play the game. I usu. play monarch/emporer, and I'll play warmongering with early war, peaceful builder w/ modern war, or straight peaceful. I'm with Sirp - I find that it's too easy to manipulate the ai into being too peaceful. I can always win on monarch and win 80% of the time on emporer following a builder strategy - on a standard map with 5-8 civs, I'll have maybe 6-12 cities. I'll keep a very weak military and concentrate on infrastructure, especially commercial improvements. Next thing I know, I'm generating tons of cash, I quickly buy enought techs to be competitive, and I'm bored bcs the ai never attacked when I was weak. A human player would definitely have been more aggressive and attacked me while I was technologically behind and militarily weak. I think in MP you will find your human opponents to be more aggressive, rather than less. The difference is that they will be more malleable - a human player will quickly go from friend to foe for an advantage and won't stay pissed like the ai. Also, human wars will tend to be more intense and much shorter.
