Four hundred years have passed since the last Blight was successfully prevented by the Grey Wardens. Now once again the fearsome Darkspawn under the rule of the Arch Demon gather and are about to invade the land of Ferelden. The first battleground: the destroyed city at Ostagar, where the Grey Wardens meet the army of Cailan, king of Ferelden, to try and stop the Darkspawn, preventing death and destruction before it has even begun. However, during the battle, the forces of general Loghain inexplicably abandon the battlefield. As a result, the Grey Wardens, the king, and most of the human warriors are killed. Among the few survivors is the hero, who had joined the Grey Wardens just before the battle, and must now find a way to unite the races of Ferelden in a struggle against the common enemy.
Dragon Age: Origins is a party-based third-person perspective role-playing game. Combat is in real time, with the ability to pause at any moment. Tactical options include an editor which allows the player to give the AI detailed instructions on how to behave in every possible situation. The player can also control the party (with up to four active combatants) one by one, switching between the characters, using their special talents and abilities to overcome the many different enemies. During the course of the game, the player will have the opportunity to invite up to nine players to his party. While only four can leave the party camp at any given time, the experience points earned by killing enemies, fulfilling quests or simply opening a chest are granted to each member of the group.
Dragon Age: Origins allows for character development through level-ups. Each character earns three attribute points and one talent point at each level-up. The talent point is used to unlock new spells and abilities in the extensive talent tree differing greatly between the three available classes: warrior, rogue, and mage.
Characters also earn skill points every three levels, allowing them to learn or get better at herbalism or increasing survival skills. At level 7 and 14, characters earn a specialisation point which allows them to learn two of four class specializations. These specializations give instant bonuses to certain attributes and unlock five exclusive talents.
Not everyone is willing from the start to teach the protagonist. The player's party members have a certain level of trust and satisfaction, which can range from -100 to +100. Satisfaction is influenced heavily by the decisions the player makes during the game. Talking and giving gifts to the party members also increases their satisfaction.
It is possible to have a romance with up to two of the party members if the player character is of the right gender and makes the right dialogue choices.
Dragon Age: Origins features six unique prologues, which tell the story of how the player's character met the Grey Warden Duncan and ended up at the battle at Ostagar. The console versions lack the tactical overhead view available in the PC version, but offer easier controls.
The default difficulty level on the consoles is lower than on the PC.
