I think it be awesome even if they only had one male and female voice like mass effect or two male and two female like dragon age inquisition to save money a voice just makes your character feel so much more alive
For me it depends a
lot on the VA, and how they choose or are told to do the voice. Worked well in DOS, was okay in DA2/I, but found FO4 and Mass Effect too jarring (both were way too shouty; I think even more jarring once I realised Jennifer Hale had a much broader range which included non-shouty voices, such as the female half of Lutece in Bioshock). Or the Divinity II approach where there wasn't PC-voiced dialogue but my character would comment randomly on various places and events ("ooh, shiny!")
