The latest issue of PC Zone mag got a hold of id's John Carmack where he talks more on the upcoming free-to-play Quake Live.
He affirms the browser-based game will be ad-supported but that eventually id could have "some kind of a premium service," they just have to wait and see how things go.
"In the beginning Quake Live will be completely ad-supported, it's not out of the question that eventually we'll have some kind of a premium service," said Carmack.
"But we don't know what it's going to be yet, and we're certainly going out with the completely free-to-play model. As the community grows and we start seeing what people actually want to get out of it we may offer some other things there."
He explains that the whole game project is still "very much an experiment", presumably to gauge what kind of interest and numbers come flooding in. The studio will have to watch how things develop "marketing wise" to see if gamers are hungry for something more.
"There could be a huge possible range of successes that we could see on here," he added, "and if Quake Live does well we could end up keeping people on here indefinitely, growing the community, polishing things up, adding new content. As long as it can be supportable like that."
Issue 198 of PC Zone is on sale today.
