Sacrifice

In Sacrifice, players control wizards, looking over their characters from behind. Each match starts the player with a wizard and an altar. Using the keyboard and mouse, players move their wizards around a virtual world, directing armies and casting spells to eliminate their opponents. A player's wizard defeats an opponent by desecrating his or her altar through the magical "sacrifice" of a friendly unit. Wizards can cast spells that harm opponents (combat spells), heal damage taken, or summon creatures. More advanced combat spells affect large areas of the battlefield, taking the form of tornadoes and volcanoes. Casting spells requires energy, which the game represents in the form of mana. Recovery of mana is slow, but a wizard accelerates the process by staying close to his or her altar. Close proximity to one of several fountains of mana scattered across the world increases his or her recovery rate as well. A wizard can monopolize a mana fountain by erecting a structure known as a manalith over it. Because mana can always be regained, it is an infinite resource. Souls are the other type of resource in this game; they are used, along with mana, to summon creatures, who form the mainstay of the players' offensive capability. Unlike mana, souls are limited in quantity. Players start with a few souls and increase their resources by locating unclaimed souls, or by converting the souls of unfriendly creatures their wizards have killed. Summoned creatures are mainly classified into three classes: melee, ranged, and air (flyers). In a rock-paper-scissors manner, each class is a counter to another. Melee creatures inflict more damage to their ranged opponents, but cannot retaliate against flyers, which in turn are vulnerable to those who can attack at range. Several creatures also have special abilities, such as creating protective magical barriers, becoming invisible, or immobilizing their opponents. Two units, manahoars and sac doctors, have special purposes. Manahoars help to recharge their summoner's mana by channeling energy from manaliths to him or her. Sac doctors are summoned to extract the souls of fallen opponents and bring them back to the altar for conversion. These units are also summoned to hold the sacrificial rituals required for desecrating enemy altars; killing a sac doctor disrupts the process. The spells and abilities of the creatures are designed along the ethos of five gods. Persephone, the Great Healer, bestows her followers with powers of regeneration and nature. Her counterpart, Charnel, God of Strife, celebrates death and decay; his creatures are undead and his spells drains the life of others. The other three gods—James, Stratos, and Pyro—govern natural elements, granting their followers abilities associated with earth, air, and fire, respectively. Unlike other real-time strategy games released in or before 2000, Sacrifice's gameplay is not focused on large-scale management of resources and bases. Instead, the game emphasizes micromanagement of the players' units; success in the game is linked to meticulous control of individuals or small groups to overcome enemies. Players order their armies to assume formations by pressing an assigned key or navigating through a pop-up menu. The order can also be given by moving the mouse in specific patterns without waiting for the menu to appear.
