Man... the writing and voice acting wasn't great. I don't think any of the NPCs were interesting. They just feel like overblown stereotypes. None of them seemed to have the nuance and depth of the characters from The Witcher 3.
The dialogue was pretty bad... But this was just a taster to give a feel for the game. It's not representative of the final product. I'm sure the characters will be fleshed out more and the dialogue worked on, given the most common criticism and feedback to CDPR is that the dialogue is cringe worthy.
