I'm stuck on the fence with this one, I think that the silent and voiced protag's both have significant pros and cons.
I liked the roleplaying aspect of Origins, a lot friendlier to everyone's headcannons. I also liked the large amount of dialogue options that were presented for the player and I felt less pigeon holed into one of three personalities. I struggled needing to fit a personality, I don't need to be a schizophrenic character but not everyone is going to always be good/bad/sarcastic. I felt that it left no room for shades of grey, there was no room for a morally ambiguous character. Especially in Mass Effect if you weren't always good or always bad you were heavily penalized for that at times.
However, it was nice to see emotions while your character is delivering dialogue. There was more depth added to the character, which I believe, at times, had a much greater impact on atmosphere and overall mood. I quite enjoyed playing a sarcastic Hawke, I personally felt that Jo Wyatt did a great job hitting all the right notes for fem!Hawke.
But then there is Inquisition... I really did not connect to Alix or Sumalee's voices, in fact I really struggled with them. My first character playthrough was with Alix's voice (because hello, Traynor
) but I just couldn't immerse myself with the character. There were lines that I just cringed when I heard them and it made me a sad panda, lol. I think with a silent protag the game could have come across as quite awkward simply because all the other vo's were so lively and animated and it would have made a silent protag quite inadequate. But, in saying that I may have been able to immerse myself as the Inquisitor if there were silent.
