How does Civilization IV: Colonization differ from Sid Meier's Colonization?

In addition to updated graphics engine and a multiplayer segment, Civilization IV: Colonization has many new gameplay mechanics. When starting the game, in addition to choosing a starting European nation, a player chooses between two governors, each with different advantages. In addition, national borders is a gameplay concept taken from the Civilization IV game. This means that rivals cannot pass into each other's land unless they have an open borders agreement - or by declaring war.





Unlike the original game, nations cannot recruit the same founding fathers. Each founding father is recruited by one and only one nation / player. Moreover, founding fathers will only join nations with certain criteria, namely a certain level of "points" obtained in various categories (political, military, exploration, religion, and trade).





After the player declares independence, players draft a constitution determining the government style of their independent nation. For example, if a player chooses a monarchical system, then he can still trade with Europe during the war for independence.





Unskilled citizens are placed in a school or college to learn, rather than a skilled colonist being placed in that building to teach.





Settlements now have build queues. If tools are not present but are required to complete a construction, the next building in the queue may commence. When the required tools are available, the pending building can be completed without affecting the current construction.





In the original game, a treasure train took up the entire 6 slots of the cargo hold of a Galleon. Now these ships carry treasure in a single cargo slot, allowing them to transport six.





All Indian settlements train more than one colonist. In the original game, only the capital could do that, the other settlements refused further training after the first one.
