Keep Moving.
Adventure games (i.e Gabriel Knight series for one) have obviously been doing the full speech thing a long time before the immersive 3d first person rpg.
But I think as virtual worlds and roleplaying games get even larger and the technology advances likewise along side it, the concept of a fully voice-driven game world does become more interesting, sure. Whether any of us will be alive to truly see the full realisation of the idea, is another question. [img]smile.gif[/img]
So providing the gameplay mechanics and roleplaying depth involved isn't 'dumbed down' in any way and there is enough text to keep me happy, I probably won't mind with Oblivion.
