What are your favorites? I hope, as always, this isn't considered spam. Nice quips from foes in a game can make it feel more badass I think, in others, it can make it more interesting. It was unfortunate to me going into Arkham City when it was somewhat similar to Conviction, yet no one swore at me. Also, I didn't notice it in the game, but there seems to be only one person doing the character sounds in Splinter Cell: Conviction.
Edit: Sorry, I messed something up when inserting another video.
