Doom 4 faces challenges in its development.Doom 3 Facebook page

id Software's Doom 4 is plagued with development troubles ever since it was announced that the game went into production in 2008. However, Kotaku reported that its development was trapped and the game suffered from mismanagement and its development was completely started form the scratch from 2011. Now news about the game has emerged again, this time during the twentieth anniversary of the release of the first Doom game.

John Carmack, co-founder of id Software and now CTO at Oculus Rift VR, in an interview with Wired to celebrate the occasion of twentieth anniversary, said that id Software had trouble finding out the essence of Doom and the best way to go forward for its delayed release.

"It's been hard-one of the things that was a little bit surprising that you might not think so from the outside, but deciding exactly what the essence of Doom is, with this 20-year history, is a heck of a lot harder than you might think. You get multiple Doom fans that have different views of what the core essence of it is, and there's been a design challenge through all of it," said Carmack.

Carmack did not reveal much about Doom 4, saying he cannot go into the details of the game. Doom 4 went through some more challenging issues in its development. 

"The worst aspect of the continuing pace of game development that we fell into was the longer and longer times between releases," he added.

"If I could go back in time and change one thing along the trajectory of id Software, it would be, do more things more often. And that was id's mantra for so long: 'It'll be done when it's done.' And I recant from that. I no longer think that is the appropriate way to build games. I mean, time matters, and as years go by-if it's done when it's done and you're talking a month or two, fine. But if it's a year or two, you need to be making a different game."

id Software has not been able to consolidate what the next Doom will feature, nor has it been able to give fans a game until Doom 4 arrives.
