Dragon Age 3 was originally touted as an open-world game in the style of The Elder Scrolls: Skyrim. However, this is not the case. Bioware has indeed been examining Skyrim, but only in the sense of exploring how to make the game world of Dragon Age 3 bigger, more varied, and more open to exploration than what we have previously seen in the Dragon Age games. A very common criticism of the series, especially of Dragon Age 2, was that a lot of environments were repeated.
With Dragon Age 3, Bioware hopes to eliminate that. The world of the game is supposed to be huge. One map is reported to be four times that of the map of Ferelden in the original game. Although gamers have yet to see it, one can only hope that players will be allowed to see much mentioned places like Tevinter and Orlais.
From the looks of things, Bioware is making Dragon Age 3 one big game. So it only makes sense that a game this big comes with a big plotline. The stakes are high in the world of Thedas. As a result of Dragon Age 2, mages and templars are at war with each other and the resulting chaos has caused a tear in the Fade, the magical realm that is host to demons and other very bad things. It is up to the player to calm things down.
As Bioware has put it, the main plot will be “saving the world from itself”. The player is supposed to take the role of a of an inquisitor, leading a politico-religious inquisition to restore order to the world. Hence the game’s subtitle, “Inquisition”. By the looks of it, things are going to be very serious and consequential in Dragon Age 3.
