By that I mean the same way Avatar revolutionized 3D LA Noire has done the same for facial expressions in video games. No other game has come even close to what Rockstar did in this area. I played the Infamous 2 demo and it was amazing to see the difference and how far ahead LA Noire was in that area.
Besides that the game feels a bit empty as far as things to do. You get called in for street crimes as you go from case to case, but besides that nothing else. Yes I looked for a few hidden cars, skipped the golden reels so after that nothing else.
I think its a must play to see how improved the graphics are in games and the story line was good as well so why not give a shot.
