Witch hunt drastically changed my views as well... i had played aa fairly straight forward Warden, making all the "good" decisions. Then i got to WH.. Throughout all the other play-thrus i did, it was always Warden mage, Alister, Lillian with love interest, and Wynne, i hadnt really spent any real time with Morrigan, didn't hate her for performing the ritual and leaving saving our lives.. he had a life in Denerim, with Liliana and advising king Alister... he had no real reason to hunt her down, other then pure curiosity. But shortly after finishing it, i realized i wanted a bit more out of my own warden's story. After considering all possible outcomes and endings and what not, I started over fresh, this time making what i felt was better choices in the world. Instating King Behlen for instance, he may have been two-faced and a bit "evil" but really that was just how all dwarf nobles are when playing the political game. I also chose to do more with Morrigan in the romancing. which to me of all possible romances i enjoyed hers the most... you go thru a lot more with her then with the others... there's the kissey phase, then the "screw you we love each other" phase, followed shortly by the "you want to involve love?" phase, it goes all over the place. ultimately Morrigan became the woman my warden loved, and true to his word "I will find you." he goes after her, ending with morrigan finally being able to accept the love back, and the two of you go thru the mirror together to raise a demi-god son... (two mages, born from extremely powerful mage lines, with an old god essence? yeah that child will do just fine...)
When DA2 came out and i had done a couple of play thrus, (mostly as mage) by the end of it all when hawke left i kinda like to believe hawke and isabella jumped on the ship he got her, and perhaps ran into his cousin, offering their boat as a means to travel easier, together.
seeign that final scene with the seeker and liliana, it made me feel all the more better ove rthe decisions i made in that last Origins play thru.. everything just seemed to fit.. i dont think hawke and the warden were meant to fight eachother.. and tho i htink its a bit much to expect my warden as a companion character in DA3, it'd still be nice... perhaps they'll have to join forces to take down the most powerful demi-god child? haha
