@LazarouDave You're right about Yuri, but other than that, a playable character whose voice is heard at a rare point of the game is different from one who commonly speaks.

@ Pigpen077 Price/Elias talked because they were mostly NPCs, and were only playable at specific moments, so they're not really counted.
