Birthright: The Gorgon's Alliance

Birthright: The Gorgon's Alliance is a 1997 strategy computer game developed by Synergistic Software and distributed by Sierra On-Line. The game is based on the Birthright campaign setting for Dungeons & Dragons and is available for DOS and Windows.

Plot
Birthright: The Gorgon's Alliance is a real-time strategy game where the player is one of the heirs to a throne, a descendant of the royal bloodline on a quest to take over the world.

Players take on the role of ruler, or regent as they are called in Birthright, of a nation in the Land of Anuire on the continent of Cerilia. The objective of the game is to gather power and influence while the other regents try the same.

In order to accomplish this objective, the player may use warfare, diplomacy, magic, manipulation of holdings such as guilds and temples, the establishment of trade routes. All of these actions take place in a turn based fashion on the world map, with the exception of the adventuring, which is done in real time 3D.

Gameplay
The adventure game engine was a Doom II engine clone: a 2D/3D engine which has essentially a flat layout map which used three resolutions of avatars that were hot swapped in depending on the distance from the viewer and the amount of memory on the hardware. Also there were flying wyverns and spiders which crawled on the ceilings as well as the floors.

If the player failed to equip their spell caster with the necessary spells before adventuring those spells were unavailable to them and forced the player to leave and re equip.

Battle system
There was also a battle component to the game. When armies met on the world map the player could select to let the computer do dice rolls and determine the outcome based on the character attributes. Or the player could enter a battlefield. The battles were turn-based and fought on a grid that was copied from the paper game. The game engine used the same engine as the adventure game. The battlefield being essentially one large room. The avatars were used to represent the unit's health. As the unit was wounded the avatars were "killed" off until it was destroyed or a dice roll forced them to flee the field. The defending army would get to pick the terrain type. There were fields, marshes, woods and a mountainous terrain. An elf army would get a bonus for fighting in woods, dwarves get a bonus for the mountains. There were some obstacles like water or trees through which the army could not advance or lost its charge bonus.

In order to win the game, a certain amount (depending on difficulty level) of (game) points were required to be collected, for example by taking control of territories allied to or belonging to the Gorgon. There were a number of successful ways to win this game.

Reception
According to GameSpy, "players justifiably ignored Birthright: Gorgon's Alliance, which eventually sunk into well-deserved obscurity".
