Voice acting and dialogue play an important role. It wasn't Stobbart alone. I can't recall a single character that I liked. The dumb french gendarme, the fat british lady, the thugs outside the hotel, the hotelier... they all annoyed the fuck out of me. When I FF through the majority of dialogue, potentially skipping important plot details, I start asking myself, why do I even bother. I get that a lot with newer fully voiced adventures. Maybe I should play with VA off, but if it's there it should not suck imo.
