Players
Included in the Player Data tab, one can edit details of the players, this includes their civilization, resource count, name, color. AI, and team number.

Objects
The former "units" tab has been replaced with Objects. Under this tab one can filter the following. The tab is organized such that navigation is more easy than in previous versions. If too many units are placed on the map however, the game may lose performance which may vary depending on the amount of objects placed and the abilities of the player's operating computer. Placing too many units, especially with AI, may worsen this issue.
 * All
 * Units (Infantry, Cav, Heroes, navy)
 * Buildings (All buildings including special campaign pieces)
 * Embellishment (visual elements such as fire, rain, and plants)
 * Nature (tab includes sockets for natives and trade routes)
 * Current (A listing of all objects currently on map)
 * Test

Triggers
This feature enables the player to create and activate a variety of effects once certain conditions are met.

There are three basic elements of a trigger and are as follows. Triggers can be used to enhance scenarios, simulate many genres, and even recreate the campaign.
 * 1) Trigger
 * 2) * Name (Name of the trigger)
 * 3) * Options (Set whether the trigger is active, will loop, or run immediately)
 * 4) * Priority (Set importance of trigger from high to low)
 * 5) Conditions (Specify conditions for trigger's activation)
 * 6) Effects (Specify what the trigger will do upon activation)

Clever use can allow players to create their own story-lines and multiplayer minigames. One feature players have access to are the game's sound files. These include, but are not limited to all music found in the campaign, voice dialogues, and sound effects.

Players may also add their own custom sounds by adding files to the game's folder.
