Peter Dinklage’s voice work in the Destiny alpha is one of those gaming memes that transcends knowledge of the game in question. We leave it to readers whether or not that’s deserved. But that’s not why Dinklage is being replaced by Nolan North as a voice actor; according to Bungie, Dinklage’s Hollywood schedule simply means that he’s not readily available to record voiceovers on short notice.
As reported previously, North will record all of the lines for the player’s AI companion in both the base game and The Taken King. If you’re worried about the length of the latter, you can rest assured that this expansion is going to be substantially larger than the game’s previous DLC offerings, so purchasers can expect more than snazzy new Nolan North lines (which may or may not include discussions of wizards and their descent from planetary satellites).
