6. Unlimited Modability: Civilization was one of the first major games to be user-extensible, and Civilization IV takes this to extremes. In addition to the built-in world editor, the game is built with the open source Python scripting language, allowing users to easily modify most features. For more hardcore modders, the SDK will be released in early 2006, and will give players the ability to change virtually everything about the game, from the way the AI behaves to the position of the camera.

7. Really Awesome Multiplayer: There are so many multiplayer possibilities with Civilization IV, that this requires two entries in the list. Aside from all the neat tweaks to keep things going smoothly, there are now lots of new gameplay possibilities. Team games are now easily set up, and teams have new ways to communicate with each other, from annotating each other’s screens (you can literally draw lines to tell people where to go – think of strategizing in football) to sending little pings to alert teammates of important events happening around their map. Support for voice over IP allows players to talk to each other while they play, whether it’s for genuine communication or just plain smack talking.

But that’s just the start of the multiplayer possibilities with Civilization IV. The new “Double City Elimination” option means if you lose two cities, you’re out. “One City Challenge” means you can only have one city. The “Always War” and “Always Peace” games limit you to one or the other. All of these can be mixed and matched to create exactly the kind of multiplayer Civ game you want to play.

One particularly hardcore game can be created by playing with teams and handicaps, so that you have two teams: one with a single person set to the easiest difficulty setting (giving that player a major bonus in all areas) and one with several other people on normal (or one of the harder levels, if you really want to make things interesting) trying to take him/her down.

Also fun: a really small map with a lot of players. Twelve people playing a game of Civ is great when there’s a lot of space. Put them all on a map the size of Rhode Island, and see how long it takes to get ugly, as still developing civilizations battle for what little space there is.

8. Custom Games for Single Players: With the Custom Game feature in Civilization IV, you can basically play a multiplayer game all by yourself. All the same options available in multiplayer can be used in single player games against A.I. You can even play with the A.I. by turning on Random Personalities. With that on, you don’t know how the A.I. is going to react. Gandhi the Conqueror? Genghis Khan the Pacifist? Both could happen. And of course, you can play a multiplayer game with two people and 10 A.I. civs, replacing them as real people join in, or start a multiplayer game where all the other players are A.I. and people can take over whenever they like.

9. Play At Your Own Pace: Civilization IV introduces multiple game speeds, so you can play a quick, normal or epic game. If all you want to do is a quick game in an hour or two, you can do that (yes, it really is possible to play a full game of Civ in a lunch hour!). If you want to spend two weeks building the ultimate civilization from the dawn of time, you can do that too. It’s all up to you.

10. Movies are Back: Civilization IV sees the return of wonder movies, a fan-favorite feature that the team wanted to bring back with a bang. Now when you spend 50 turns building the Pyramids, the Hanging Gardens or the Great Library, you’ll see a CGI cutscene of the construction of that wonder. And there are more than just wonder movies this time around…when you discover a religion, you’ll see a movie about that. When you win the game (however you choose to do it), you’ll see a movie celebrating your victory. It’s all part of making the best Civ experience to date.

11. Choose Your Destiny: With Civilization IV, there are now six different ways to finish the game. There’s the Time victory, given to the player with the highest score in 2050 AD. The Conquest victory, given to the player who successfully eliminates all of their rivals. The Domination victory, awarded when a player has a 25% lead in population over their next rival and 65% of the global land mass. The Cultural victory, awarded when a player owns three cities with legendary culture status. The classic Space Race victory, given when a player completes all the components necessary to send colonists off into space to found a new colony on Alpha Centauri. And finally, the brand new Diplomatic victory, where after the forming of the United Nations, your civilization is voted to head up the organization. Considering how difficult it is to maintain friendly relationships with all civilizations (especially given that they’re likely to be fighting among themselves), this is quite possibly the most challenging victory in the game.
