EA Access details how much of Dragon Age: Inquisition will be available the first five days:
Your membership will get you into Dragon Age: Inquisition on November 13, before the game’s November 18 release date. The six-hour trial lets you create your hero, form your Inquisition, and take your first steps into Thedas, exploring the world and battling evil in both real-time and tactical combat. Discover the Hinterlands, where the war between Templars and mages has hit a fever pitch, or gather materials and schematics for crafting your arsenal. You can even jump into Inquisition’s cooperative multiplayer missions. The choice is yours.
