If you're coming to
Dragon Age: Origins - Awakening looking for the same great experience as the first game, know you're really just coming for a chance at some new weapons, new Darkspawn and to continue what little of your character's journey the narrative leaves. When you start, you're able to pull your character from
Origins, even ones who haven't completed the main game, into
Awakening's adventure. From the start, this severs most major connections between the two games, leaving a few strands of weak connective tissue between the two.
The new plot is almost completely independent of the original and places you in charge of the new Grey Warden outpost in Amaranthine. Upon arrival, you discover your new base of operations, Vigil's Keep, under attack by a well-organized Darkspawn army. Even more distressing, some Darkspawn can speak, signaling an alarming origin of the species.
On a fundamental level, Awakenings is the same game as Origins. The only major gameplay shift is the addition of playing "governor" as well as warrior. At various points, you'll have to make political decisions like deciding where to send troops or how much to spend on upgrades to the Keep. Your choices have an impact on the story, though it is diminished slightly thanks to a tough, and somewhat cheap, endgame.
The new play mechanic and lack of connectivity to the main game cause Awakening to feel more like a minor sequel than expansion. For newcomers this won't matter, but for players with an emotional attachment to their Origin's party, it's sort of a big deal. The new crew is great, but they aren't as embedded in the overall story. It's more Mass Effect 2 and less Dragon Age: Origins. They're just people who go along for the ride and have side issues to deal with along the way.
The most memorable aspect of Origins was the amount of tension found in every piece of the story. Whether mediating the relationship between werewolves and elves, or taking part in dwarf politics, every moment felt big. I was invested. Though Awakening has its moments, none are particularly noteworthy. Even events like the Warden's Joining Ceremony and The Right of Conscription are tossed around like nothing.
