I think voice action would kill this game. We all have an idea on how are Warrior of Light will sound. I know for a fact they will not be able to give us that. Which will make us grow to hate our character. Let not forget voice acting cost money. With the PC normally having the most lines. They tend to hire cheaper voice actors for the main character. Which is shows in many games. Do you not remember Tidus? His voice acting was as pleasant as nails on a chalkboard.

I am sure more people would leave the game from PC voice acting then it would bring in.
