By comparison, the cast for QFG V isn't nearly as impressive. I guess Sierra felt they had shelled out enough for the game's development that they didn't want to pay for the big-name voice actors again. But now I'm curious, who are some of your favourite voice actors or the characters they play? Personally, I think that Jim Cummings has done some of the funniest voices I've ever heard. Just look at Darkwing Duck and Minsc from the Baldur's Gate series.
