I does have its advantages for dialogue-heavy games at least, because voice acting generally means less in-depth dialogue due to the added expense of voicing it (except perhaps in the very biggest budget games). It also allows you to use your imagination a bit more, e.g. to imagine how someone sounds. Although some text-heavy games have a *bit* of voiced dialogue (e.g. Morrowind).

Voice acting can be poor, but I think that's a bit less of an issue nowadays, except maybe in certain Japanese games.
