Dragon Age: Origins

Dragon Age: Origins (also known as Dragon Age) is a computer role-playing game developed by BioWare's Edmonton studio. The game was released for Microsoft Windows, PlayStation 3 and Xbox 360 in November 2009.
Dragon Age: Origins utilizes a new game engine named Eclipse,
for which a toolset for creation of fan-made content is to be included
with the game. The game is single-player only and does not provide LAN
support. BioWare co-CEO Ray Muzyka described Dragon Age: Origins as a "spiritual successor" to the Baldur's Gate series,though it is not based on Dungeons & Dragons.
The game incorporates "origins" for each race and some classes. For
example, a Dwarf Noble begins the game as part of the royal family in
one of the dwarven cities, whereas the Dwarf Commoner origin story
begins on the streets of the city. Origin stories determine the
background of the player's character prior to the main events of the
game's story, forming an introduction to the world while also
comprising hours of play. Characters that the player meets during the
origin story may reappear throughout the game, some of whom may be
adversaries.BioWare have described Dragon Age as being a "dark heroic fantasy" story that will be told on an epic scale with mature themes.
The player begins his or her journey from in one of the six origin
stories which serve as an introductory point for the players and
present the world from their personal point of view. The origin story
chosen (the choices being Human Noble, Human/Elf Mage (dwarves having
an immunity to magic), Dalish Elf, City Elf, Dwarf Commoner and Dwarf
Noble) determines who the character is and how NPCs react to the
player. Elves, for example, are often viewed as second class citizens.
After completing their character's respective origin story, the
player encounters Duncan, leader of an elite group known as the Grey
Wardens. Duncan guides the player to their destiny of becoming a Grey
Warden, and dedicating their life to the destruction of the Darkspawn,
a force of demon-like creatures that live underground and have at
various points in history (for a total of four before the time of the
game) invaded the surface dwellers of Thedas in massive movements known
as Blights.
The player and Duncan journey to a fortress called Ostagar in
southern Ferelden, to join the King of Ferelden, Cailan. There they
plan to make a stand against the encroaching Darkspawn, who Duncan
believes have gathered for the first true Blight in 400 years. Duncan
has sensed the influence of an Archdemon, a great being hosted in the
body of a powerful dragon, in the Darkspawn's actions, making a Blight
possible. King Cailan gathers his army, with his father-in-law and
revered hero of the nation, Loghain Mac Tir, as his commander. All
parties involved plan for Cailan to charge the Darkspawn as they
approach the fortress at Ostagar, and then have Loghain lead his forces
to flank and destroy the Darkspawn.
