Duke Nukem Forever will three times longer than COD: Modern Warfare 2
This has been assured by Randy Pitchford, CEO of Gearbox studios. According to his comments, Duke Nukem Forever will give quality of a "Triple-A" game and a campaign to triple in length to that of any current action game, one example will be three times larger than that of Call of Duty: Modern Warfare 2.
In his words:
"It's gonna be big. Duke is a big, triple-A title. The campaign is huge. It's probably three times the size of the last Call Of Duty game. And it's great through and through. Any time I play I play it, at any given moment, I'm having a great time and I want to see the next moment. There's crazy set-pieces and, in that regard... if you're expecting this to be a fizzle-out, a low budget thing, you're going to be like: 'Holy ****! Oh my God! This is no joke!".
