Morrigan won me over immediately because of her atheism. Her banter with Leliana where they debate the existence of the maker and whether faith is desirable regardless was great. Dragon Age was my first encounter with romances in RPG's besides the Witcher - and in that game it was really only a choice between two women, and then only one or two more steps before you realize you love the girl and the game is over. (There were all the one night stands of course, which were more in keeping with the Geralt of the books anyway).
