I'm really going to listen to the reviews this time, I ignored them with DA2, and...well the preorder probably shouldn't have happened. I admit I never beat DA:O, but that was just because my save got corrupted when I got to the final battle. DA2 was just...the combat was more fast paced, but it wasn't as fun as the original's more strategic combat.
The story was...eh. Your choices didn't really amount to much. I gave up about half way through. In fact, I'd go as far to say that ME3 was a better game. You may think its weird comparing a high fantasy game with a sci-fi one, but DA2 borrowed so much from ME2, it drove me mad. ME3, even being worse than ME1 or 2, at least had me gripped throughout it.
