According to Killzone: Shadow Fall developer Guerrilla Games lead designer Eric Boltjes, while developing for the PlayStation 4 is technically easier thanks to its architecture, it is also much more demanding overall from a professional perspective.
"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," he told VG247. "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."
This is because everything in the game world "needs to look that much better," which requires more staff and efficient communication, Boltjes said.
"It takes a lot more people and that takes a lot more communication," Boltjes said. "So it does it make things a lot more easier from a technical standpoint, but from a professional standpoint it makes things a lot harder."
