First I'm very happy to hear the news about galciv3! Can't wait.
When it comes to my strategy games I am almost exclusively single player. There was a post I agreed with back in 2006, by Frogboy, talking about multiplayer and galciv. http://forums.galciv2.com/98074/page/25
Has the tech changed enough that multiplayer doesn't take as many resources as in the past to implement?
I'm not complaining multiplayer is in, just curious as to the change.
