there was something forza 4 lacked, something that forza 3 had completely perfectioned. maybe the liquid dnb songs? or the menu music? maybe the multiplayer?
9 months later the truth rings out! The music industry is suffering because technically it takes 200 dollars to buy a computer and beyond that you need nothing else to make professional level tracks. That combined with piracy = 100 million artists releasing 500 million tracks a day. All of them competing for 0 dollars.
