source.The Doom 4 initially in production at id was simply "not Doom 4", publisher Bethesda's marketing exec Pete Hines told IGN.
"It wasn't one thing," added id Software studio director Tim Willits. "It wasn't like the art was bad, or the programming was bad. Every game has a soul. Every game has a spirit. When you played Rage, you got the spirit. And [Doom] did not have the spirit, it did not have the soul, it didn't have a personality. It had a bit of schizophrenia, a little bit of an identity crisis. It didn't have the passion and soul of what an id game is. Everyone knows the feeling of Doom, but it's very hard to articulate."
I eagerly anticipate your "Doom 3 and Rage didn't have a personality either" arguments.
Interestingly, the following was said as well:
Which I guess was the major complaint about Rage as well."And I think what the guys at id are working on is... they're pushing the boundaries and challenging themselves. I don't want anybody to look at id's next project and have this reaction that it's still stuck in the 90s."
