This.Uh... No offense, but how fast of a reader are you? I think reading is much more faster than listening to someone read to you, it'd probably take more time if anything, not to mention it'd take up HUGE amounts of space. Maybe voice acting for story cutscenes but that's about it.
And this too.ON these 2nd person view games like pokemon black 'n all,i don't think it will sound any good.
