Now, I am one of those weird people who tend to prefer reading text in a game over voicing. I think some voicing by key characters, especially at pivotal moments, adds enormously to atmosphere and immersion (i.e Irenicus in BG2), but for the more mundane bits I generally prefer text.
Partly, it is because I often turn down my sound when I play a game, and also, well-written dialogue is enjoyable to read, or at least I think so.
Of course, now the trend is largely toward complete voicing ... but I'm a dinosaur. Is there anyone else here just as reptilian and scaly?
