Fuck no. I beat the main game, didn't bother with the DLC, and I'll say this about it. Honestly, the ending was pretty cool, and it seemed to set up the Dragon Age that I'd like to play, but the game it self seemed like one very large footnote in the Dragon Age series, and is completely unremarkable at the end of the day. 2 is better in my opinion, and I really didn't care for 2. At the end of the day, Origins is still the only Dragon Age worth your time, and if you've already beat it, then just start a new game with a different build and enjoy a mostly different experience with all new characters and play styles.
