Haze Developer says PSN offers more freedom than Xbox Live
There isn’t much defined by Sony how you have to do things on PSN, they leave it up to the developers. So there is always a chance for developers to under deliver, but it also gives them great freedom to do what they truly want to do. But with Xbox Live they have to conform with Microsoft’s standards and has a lot more structure and more libraries available for the developers. So each has it’s pros & cons.
As far as playing Haze online they said PSN wasn’t a issue at all. They had planned for it from the start, and they’ve be able to do it how they want it. The Haze developers said “for us as a developer – the PS3 stuff… we’ve always liked working with it.”
