Here's a comparison of Tyrion Lannister and Nathan Drake doing the voice of Ghost in Destiny
Eh.... It's different but I'm not sure it's really better. Then again, I have heard Dinklage say the lines so many times that North's version sounds weird to me. People may not know this but Dinklage is not the only TV/Film actor in this game. He just has by far the most lines.
Here are some of the other voice actors in this game. Just thought this was interesting since much of this talent seems to be wasted. You can see where a big chunk of the game's budget went.
Bill Nighy (Shaun of the Dead, Harry Potter, Pirates of the Caribbean)
Lauren Cohan (The Walking Dead)
Gina Torres (Hanibal, Matrix franchise, Suits)
Lance Reddick (Fringe, The Wire, tons of movies)
Nathan Fillion (Firefly, Castle)
Lennie James (Jerricho, The Walking Dead, Snatch)
Peter Stormare (Fargo, The Big Lebowski)
James Remar (Dexter)
Erick Avari (Lots of movies)
John DiMaggio (Futurama)
