Don't be alarmed lazy gamers, for this does not mean that you are required to swap discs frequently. Rockstar has stated that the switching will take place in "natural breaks". Seeing as how the game will keep you on the edge of your seat anyway, this does not seem to be too much of a problem.
So 3 discs equals 3 times the average game? Not at all. As I stated, the space is mostly filled with the phenomenal cut scenes that take place regularly throughout story. The game is rumored to be around 25-30 hours long give or take; so all-in-all the game is still a decent length.
Fortunately for Ps3 gamers, the epic will fit unto the blu-ray disc, surprise surprise. So go ahead and chuckle you Sony fanboys.
L.A. Noire will be released for the Xbox 360 and Ps3 May 17th.
