Call of Duty and Battlefield are the only first-person shooter franchises making money, TimeSplitters developer and Free Radical founder Steve Ellis recently told Edge. As a result, the longtime developer believes publishers are wary to green-light projects that buck established trends. Publishers won't pursue a unique FPS, according to Ellis.

　　"I spent the whole of 2008 going round talking to publishers trying to sign up TimeSplitters 4," Ellis said. "There just isn't the interest there in doing anything that tries to step away from the rules of the genre--no one wants to do something that's quirky and different, because it's too much of a risk. And a large part of that is the cost of doing it."

　　Crytek UK (the name Free Radical took on when Crytek purchased the outfit) recently confirmed that TimeSplitters 4 was not in development despite the game having been announced in 2007.

　　"Nobody really buys any FPSes unless they're called Call of Duty," he elaborated. "I guess Battlefield did OK, but aside from that, pretty much every FPS loses money. I mean, [look at] Crysis 2: great game, but there's no way it came anywhere close to recouping its dev costs."

　　Ellis left Crytek UK in February 2009 to open a mobile game studio called Crash Lab. He explained that the FPS genre today has morphed considerably from what it once was.

　　"We've been through more than a couple of console generations and seen things grow and grow to a stage where it's not really the business we got into," he said. "It's not really what we signed up for at the start."
