Dragon Age Inquisition had 2 possible voice options for male and female players. I think for my 800+ hours of player time (yes, I liked the game a lot ^^) I think I tried the alternative voices for both genders once. Honestly it's just not worth it.
Like you I liked DA: Inquisition a lot, but I really apprechiated the choice betwee two distinct set of voices. My flimsy aristoratic mage sounded different from my no nonsense fighter.
That said, quality over choice in this case and recording two sets of voice acting per gender will be expensive.
