I'm don't mind the new system. But it's pretty clear your character is not your own. Similar to ME (but Shepard had history and therefore you had a connection with the guy, assuming you played all the games/dlcs).
DAI did a better job with voice characters. BW just does a better job in that regard.
Frankly, I don't care about "my" character. There's no emotional connect at all between us. I feel more for Valentine then I do my own character. What's keeping me playing isn't "him", it's the side quests and the companions.
But biggest worry is modding. Does this mean we won't be able to create new quests and stories lines? Cause adding another actor to fill a voice, or suddenly turn the voice off would not be cool. Maybe Beth needs to add a mode where we can turn his voice off - rely on the subtitles? If we have access to the voices; how many words have been created? Are they words or phases or just dialog?
If this can't be modded, then this game is done for me. If all we can mod are bug fixes and environmental, immersion mods - that would be messed. That WOULD be a serious step backward. That would turn this game into another COD - just with a bigger world.
And then I'll start worrying about what they are going to do with TES.
