Just how long should it take to make a game before you start seeing all of your profits go into development?
Shrug. really, Polyphony Digital is a 1st party game developer. Everything they create, every innovation, every new technique is probably documented and available to every other developer. I don\'t think you can compare on a compagny that as a budget for a game and need to sell X amount of copy to become profitable.
They will also, like every other GT game, sell millions of copies and probably be a "system seller". This will be again, another profitable adventure for Sony.
Finally, if there was as many GT games as there are COD game release, people would be bored. It\'s not like you can add hundreds of new feature in a racing game every year.
