I don't really care about voice acting either, and i think Larian going all in on it this way is actually damaging to the ability to roleplay properly in the game. Having said that, I basically will not notice voice acting quality unless it is truly terrible. My scale only has two levels, terrible and fine. VA is never going to be the thing I remember about an rpg like this. Also...I'm not sure if Jason Isaacs is a big enough name to hang on the marketting like this anyway. He's certainly not as mainstream as the guy who plays Kethric whose name has suddenly vanished from my head.

Frankly i don't think any of these trailers have really shown off the game's true strength; the number of choices you can make and the flexibility of the game outside of dialogue. Hell, for all that they're front and centre in marketing, I don't think they've ever really focused on the origins in trailers either.
