I liked it that the ending was a bit ambiguous (sp?), with Morrigan becoming pregnant from Loghain to protect my character. I wonder how this will come to play in the sequel. Morrigan *did* seem genuine in her intention about not having a darker purpose. What if you choose to sacrifice yourself? How would they make a sequel?
I was a tad disappointed in Alistair in the end, though, that he wanted revenge on Loghain. I found it a lot more fitting to make him attone by becoming a Grey Warden. Do you always have to choose between Alistair & Loghain?
I really liked the tough choices, in the end.
The ending screens were a nice wink to Fallout, I think.
The soundtrack was good, with the openingtrack, Leliana's song and the endtheme being phenomenally beautiful. The rest of the soundtrack was ok, but I would have liked it a little more epic, bombastic. More Hans Zimmer-like, to compare it to something. I have a feeling Jeremy Soule might have done a better job.
I only have one "big" gripe with the game, and that's the freaking lack of numbers in the skill descriptions.
BTW, feel free to tell about other endings, since I'll probably replay it in much the same way anyway.
