What's really about this game is the facial recognition system. You see every wrinkle, every crow's feet, and can see everyone's reaction face when you interrogate someone. It is truly one of the standing points of L.A. Noire.

Overall this game is truly an innovation and a different approach from Rockstar's usual games but, it is possibly the best game right now on the market. Also, the Xbox 360 version is 3 disc so you will be disc swapping. The PS3 version comes on a single Blu- Ray disc though.
