You are correct in some ways, such as dedicating all your senses while giving you less on average to engage them, but are also over generalizing by saying it's always terrible voice acting, which just isn't true, it can be anime hammy, but I happen to really love well done over the top anime voice acting, which is a whole different style compared to something extremely realistic like The Last of Us. And if you don't like that style, that's okay, but it's not terrible.

I feel like biggest representatives could go to things like Danganronpa, Phoenix Wright, or Persona, which all feature choice and gameplay, and I'd say Danganronpa and Persona have good voice acting, with Persona's as excellent. I feel like generalizing that fans of the genre don't care about choice is just not correct for all fans, I personally dislike most of the choiceless VNs because they then rely extremely hard on story, for example I disliked House in Fata Morgana because that's a "reading a linear book" style of VN with no voice acting, and it's really long, and the soundtrack was not super amazing (compared to Phoenix Wright, Danganronpa, and Persona, which have OUT FUCKING STANDING soundtracks, and with a manga you're not getting a soundtrack that emotionally engages you and brings you back to listen to them long after completing the games as I have with those series.
