Randy held an interview with a German mag:
Gearbox CEO Randy Pitchford says he was offered to develop an entry in the "Call of Duty" series but declined the offer because he felt it would not be a "significant challenge".
Pitchford says (translated from the german text): "I don’t think there’s anything to accomplish there. I think if I was only in it for the money I would’ve done that.[...] I think to do “Call of Duty” right you need to do what needs to be done and there are a lot of people who can do that. For us it wouldn’t add to our credibility, it wouldn’t move us forward. There would be no significant challenge that would be gratifying to overcome"
Pitchford also attributes the immense success of the "Call of Duty" franchise to its reliability. Because every new installement is a guaranteed hit in an often unforseeable marlet the series gets unrivaled support from retailers. "It's becoming a self-fulfilling prophecy, to a degree", says Pitchford.
