I loved my Hawke. She was so pretty and funny and cool, I could watch her joke around all day, taking the ******, being a smartarse. Played through DA2 three times with a humourous Hawke because it was so great. I'm probably the only person in the world but I think it was a brilliant game.
But I hate my Inquisitor. I thought she was supposed to be clever. I keep picking the "clever" dialogue options and all I get is soft-spoken boring smugness. And don't even get me started on the American option...
According to the wikia "Based on dialogue options the player chooses, Hawke can exhibit three distinct personalities.
Diplomatic/Helpful: light green/light blue highlight (olive branch/angel wings and halo)
Sarcastic/Charming: purple highlight (comedy mask/diamond)
Aggressive/Direct: red highlight (fist/hammer/twin swords)
The first dialogue choice the player chooses sets Hawke's personality. If the player frequently chooses dialogue from the same type, that attitude will "stack". If the player decides to change Hawke's personality, one of the other two attitudes must be selected more than twice as many times as the current one has. The idea behind this system is to ensure a consistency in Hawke's delivery throughout each Act (though past a certain point, Hawke's personality is effectively crystallized as there will not be enough dialogue remaining to 'overcome' the dominant attitude). The current personality can be confirmed by having a companion right-click Hawke (if they say something funny, for example, they are sarcastic/charming). At the start of each Act, Hawke retains the established personality, but the "stack" of previous choices is reduced, making it easier to change Hawke's tone."
So your voiced Hawke had a distinct personality and the lines that were delivered at important plot junctures would vary depend on this, but the outcome would be the same. I've clicked on the direct option for my Inquisitor and she got randomly really angry and yelled at some people like wtf, the rest of the time you are a smarmy, irritating little elfgirl. I don't know why all the companions are so in love with her.
So is having a silent protagonist better than a protagonist that you actively dislike? Ummmm, maybe. But then you'd miss out on the chance of having one that you utterly adored.
