Speaking to Official PlayStation Magazine, Infinity Ward boss Vince Zampella announced that the team had been wanting to produce a modern warfare game for years, but Activision held them back.
"With Call of Duty 2, we were dead set against it being World War 2," Zampella told OPM, "but Activision really wanted it, the compromise sort of being that we'd get some dev kits for consoles in exchange for doing a World War 2 game."
"We always wanted to be on consoles and Activision saw us as more of a PC developer," Vince said.
"And something I'll add to that, Activision also did not want Modern Warfare. They thought working on a modern game was risky and (thought), 'oh my god you can't do that, it's crazy!' They were doing market research to show us we were wrong the whole time."
"We had to fight for everything," said Jason West, CoD project lead. "They wanted it to be World War 2. Again."
Luckily for us, Activision went with the idea, and are now bathing in the success of 14 million copies shifted worldwide.
"It just blows us away. I'm still reeling from it," Zampella said of the success.
