As much as I love the idea of all these guys being in a game, I can't see their voices sounding right with the robot effects. It would all be funny, but then all seriousness from the game would be gone when the Ghost speaks. I would love to hear the Ghost saying "mother -blam!-er" all the time, but Samuel L. Jackson would just be Samuel L. Jackson, not the Ghost (i.e. You wouldn't hear it and think "that's the Ghost," you'd think "That's Samuel Jackson!" You wanna believe the voice is from the character, not the actor reading the lines.)
