A couple of quotes by Dan Houser

"Johnny is a very different character than Niko, with a very different background," says Dan Houser, vice president of creative development for Rockstar Games. "I can't go into too much detail on the story, because we try not to give away too much plot before the game is released. But I can say that the story will show you a different side of Liberty City."

"The story is not directly impacted by decisions you took in the main game, tons of details and mysteries from the main story get explained, so it will add a lot of color to the main story."

"We feel like we've only scratched the surface in terms of the depth and detail in Liberty City."
