Warlords IV: Heroes of Etheria

There are ten different races in the game: Knights, Empire, Elves, Dark Elves, Dwarves, Dragons, Undead, Demons, Orcs and Ogres. Each of these races has six types of units, each of which has a counterpart with the other races. These unit categories could be classed as: Infantry, Archer, Cavalry, Siege, Creature, and Hero, in order of how many turns it takes to produce them. Infantry are typically the cheap, weak units. Archer units can fire projectiles, and are best used as backup for other units, as they can still fire arrows as support even when they are not the active units. Cavalry units are mounted riders who have a good range of movement out of battle, and are more powerful than infantry in battle. Siege units are most useful when attacking a city; they can stay in the "back row" (i.e. not active units) and fire projectiles at a city's walls in order to destroy them and prevent them from firing arrows at the active unit. Creature units are generally large and/or powerful fantasy creatures which are more powerful than cavalry units; they are also often flying units, which have the best range of movement on the map. Hero units are powerful units which can make use of magic items found in ruins to increase their skills. They also have a special "leadership" ability which can increase the power of other units. These categories are loose, however. While all units correspond to each other, some races have units in these slots which deviate from these categories. Units can gain experience points, and thus can gain levels, making them more powerful and allowing them to increase their special abilities. However, even a very powerful unit can be defeated by weaker units.

Each of the units has the characteristics of its race. For example, the nature-oriented elves have treants, unicorns and elven warriors as units, while the undead have skeletons and liches as units. The races also have distinct architectural styles in the looks of their cities. Each race has a strength or weakness compared with another race. This means that certain races while facing other races will have an advantage. Each character (warlord) a player makes has to have a certain "favored" race, which means that the character will produce only that race's units in his/her cities. If a player conquers the city of another race, he or she can produce those types of units, but depending on how opposite that race is from his or her favored race, it will take longer or shorter than it would for his or her own units.

The player's character is called a warlord. The player chooses one of 33 portraits to represent the warlord during its creation. The player must also choose two types of specialization for the warlord. For example, picking "combat" and "combat" will result in a non-magic-using warrior. Picking "combat" and "nature magic" will result in a ranger, and so on. The warlord can only enter direct battle when its capital city is under siege. Naturally, it is the most powerful type of unit in the game. In a normal game, when a warlord is defeated, all its cities become neutral and up for grabs, and it leaves the game with generally a few experience points. These can be used to advance levels for the warlord, and allow the player to either add on a building (from a finite number of types) which gives some benefit to future campaigns. For example, adding a certain type of building might increase the amount of gold (necessary to produce new units) a player earns per city. Instead of add a building, the player may choose to increase one of four skills for the warlord. Warlords are persistent characters which can be used in an infinite number of campaigns.

Warlords IV contains a map editor which allows users to design their own world maps to play on. Various types of terrain features are available, and the interface is user-friendly. Four sizes of maps are available (50X50, 75X75, 100X100, 125X125) based on the number of squares on the map's grid. Up to 50 cities, 100 sites (surrounding buildings which can produce resources and other effects), and 50 ruins can be placed on the map. The cities and ruins are given randomly-generated names, but the player can enter a custom name or keep randomly generating names as many times as desired. The designer of the map also determines the level, capital status, garrison, and income of the cities. He or she also determines the number of players that can play the map at one time, and the race restrictions, if any.
