When games started having serious, regular voice acting, such as in the PS1 era. We already had soundtracks and a good portion of the ideas that would forge games for years to come, but we didn't exactly have quality voices at the time. We were too restricted by the hardware... but when we made the jump, MAN... I still remember how thrilled I was when I heard voices in videogames, though I don't even remember which was that first one anymore...
