According to Guerrilla Games Lead Designer Eric Boltjes, Playstation 4 architecture is really cool and easy to develop for taking into consideration all technical aspects and requirements (such as RAM memory, HDD space, Processing power and more).
Eric Boltjes also added that production cost for next-gen games has quadrupled as compare last-gen games because every aspect needs to look much better.
“The architecture is really cool because it’s easier to develop for, you get more memory, you get more hard drive space, you get more processing power so the architecture is easier.”
“It’s also a lot more demanding, because the production effort needed just to make a next-gen title now is not doubled; It’s quadrupled. That’s because everything needs to look that much better. It takes a lot more people, and that takes a lot more communication. So it does it make things a lot easier from a technical standpoint, but from a professional standpoint it makes things a lot harder.”
Guerrilla Games is currently working on Killzone: Shadow Fall, one of the launch title of Sony’s next-gen Playstation console, Playstation 4.
