Yes. Well, the current Quake project is Quake Live, and we're actually doing that internally as well. But that's multiplayer-focused, obviously. In terms of what happens next with Quake, a lot of that will depend on how the reception for Quake Live goes and whether that team continues to invest in building that out. That would be what we're hoping for, and then [we'll] figure out where we go down the road with that.

The Quake Live team is smaller. We're still not fully fleshed out [with] three teams that can work on three projects simultaneously. Even then, then you've got Doom, Quake, Wolf, Rage -- it's like there's still an odd franchise out. Plus Enemy Territory, which would lend itself with working with an external party.

"If [Quake Live] is successful, we've tossed around the idea of taking the Wolfenstein: Enemy Territory game - which was actually always more popular than Q3A in the online space - and doing a similar treatment to it with the experience we've gained here," Carmack told PC Zone.

"If Quake Live is successful, the next thing that we might look at is Wolfenstein: Enemy Territory," said Carmack, "but it's hard to see how we'd do the same treatment of it."

Wolfenstein's World War II setting was cited as the main reason behind the company's hesitation.

"You're running around fighting the Nazis and there's a billboard with [an advertisement] on it," said Carmack, noting the awkward nature of combining Nazis and Coke ads.

"The door is not completely shut for another Quake project, and I'd say probably the success of Quake Live is going to determine whether or not we do another Quake Arena project," said Carmack.
