In a recent interview, id Software's Matt Hooper has suggested that we will probably NOT see much user-generated content support for their next game "Rage".

What are your thoughts on user-created content?

As a game player, I love it. But that doesn’t mean at the same time I can’t love a BioShock or a Call of Duty 4. You can have a focused game, and do that really well. I think that’s the important thing – doing something really well. What the other games mentioned do as far as user created content, and just on that side of things, it’s like a different focus. I think there can be a separation, almost like movie genres. It’s okay to make a comedy, or a really hardcore, serious documentary. I think there are different fits.

For us personally, our biggest goal is – you can see it right now – we’re pushing on the fidelity, visually. We’re also pushing on the gameplay fidelity. Those two things are huge. For us, we’re doing things that we’ve never done before. That’s already a lot of eggs in the basket. As far as user-generated content, it’s not a huge consideration for us right now.
