He also talked about the "unholy alliance" between players and developers -- not only is the relationship beneficial for both parties (players offer their money, developers offer their time and talent), but it's also one of "mutually-assured destruction," as players can break contact with (or even just belief in) the game anytime they feel it's not fun any more, and developers can "really mess up the game, too." Everything in the game, said Meier, should be designed with an eye towards this alliance -- the AI should live to serve the player, the graphics and gameplay should engage imagination, and even options screens and load/save settings should be developed with an eye towards preserving the relationship.
Civilization Network was mentioned under a section Meier called "my bad" -- along with the original ideas to make Civ real-time (whoops) and make the tech path random, he said that the CN team had considered letting players give gold to each other on Facebook, but during playtesting, found that players never actually did. He did say that the game is deep into testing currently, and that it will allow co-op, singleplayer, and competitive gameplay, and that it will be interesting whether players play for just "a little time a day" or more than that. At the end of the talk, in reply to a question about where he saw gaming going, Meier declared that "this is the year of Civilization!" With CN coming soon and Civ V due out this fall, we can't wait to send our Settlers out into the world.
