I'm really split here... Basically because I'm in Cloud Strife777's predicament where I'm actually in agreement with a lot of the opinion stated so far.
No, I don't feel Voice work has added to gaming in an overwhelming meaningful way and its definetly not made RPGs better. I can agree that games need to get back into the "gaming part" but I also agree with Bolivar that a great story can trump having to sit through long dialogue segments or cutscenes, they're just obnoxious when the story is bad. I agree with Flying Arrow that one of the most irritating things about FFX is how much the plot interrupts the game for useless plot flub, Mi'hen Highroad and Mt. Gagazet being especially obnoxious, but this goes back to what Bolivar mentioned because Xenosaga pulls the same trout, and I never noticed because I was enraptured by the plot. I can agree with Vivi22 that voice work is not all bad and I feel it has made some games better and can be practical, but I also agree that some examples made in this thread are not what I would call crowning achievements. I mean seriously, no MGS1? Anyone? Its like the only PS1 game with good voice acting and dialogue and it's dialogue is bat-trout crazy to boot.
I'll discuss more later, when I've collected my thoughts.
