Not only you'd constantly encounter villagers and other npc's who sound exactly alike, but when there were certain quest npc's with their unique voices, you could ask them about rumous and their voice would change and they'll repeat the same generic old rumors heard from the common npc's, again, with a different voice. (i.e. when asking beggars about Gray Fox - he's a fairytale yadda yadda)
So, has there been any info about how much voice talent Bethesda has hired for the game?
