You are not alone, you can add me to the list of 'people who cried over a video game'. Well, crying doesn't always mean tears flowing all over my face, but there were some moments in the game, in which my eyes were just full of tears and I got choked up quite a bit.
The goodbye speeches in Denerim were among the most dramatic moments in the game for me. That really made me sad, like I was just about to loose my good fellows, who accompanied me through all this. The dramatic background music during that scene did quite a good job to underline the emotionality of that moment for sure. Leliana's song was about the second most emotional moment, which actually made me cry a little bit, just by the beauty of that sad, sad melody. I was not prepared for this.
The ending after the coronation also gave me a terrible feeling and made me sob here and there, when the party members say their goodbyes and go seperate ways from that point on. In general, the whole ending made me really depressive in some way. Usually, I feel good when I have finished a computer game and enjoy its ending, but not here in Dragon Age, I can't exactly explain why. On one side, the ending was good, but on the other side, it just made me feel even worse, because it suddenly was all over and it has this 'once and for all' touch.
Dragon Age is by far one of the most emotional games I've ever played in my life, no kidding. It never stops to amaze me, how far character and personality creation in computer games has already evolved. It is almost a bit scary, how we get pulled into such stories and how fictional toons, which are only made of program code, can manipulate us and wake feelings inside of us. Only a computer game, but still....
I think Bioware can't top this amount of emotions in their future games, but that also was what I thought after finishing Mass Effect.
BTW: I even cried over a book once, when I was younger and only once, but I did. So yes, you can cry over books too.
