This. There's tons of ways to make it obnoxious ('BURN TO THE-BURN TO THE-BURN TO THE GROUND!') or immersion-breaking, so many ways that dialogue and delivery can go wrong. To paraphrase the recent Extra Credits feature on the Uncanny Valley, the gap between no voice acting and good voice acting is a very wide one, and falling into that gap can be more detrimental to the experience than if you'd never tried at all.veloper said:I'd rather have no voice-acting than bad voice-acting, unless it's the rare so bad it's good comedy stuff.
Most voice-acting in games is bad. Then again, so is most of the dialogue game writers can come up with.
That said, it is an excellent way of lending flavour to a character, far faster than extensive dialogue or behaviour.
I find it strange how Metal Gear Solid, a game over 10 years old, has hours of voice dialogue and no lines that are really badly delivered. Silly yes, but not badly delivered.
