Speaking to IGN, id's John Carmack has confirmed that you won't be able to switch the in-game ads off in upcoming free-to-play shooter, Quake Live.
"No, there's no current plan for that," he said. "Not to say it couldn't happen depending on how the market bears out on it. Actually, turning the ads off right now would make the whole thing look worse. They really are integrated in such a way that they're not obtrusive, you're not waiting for any of the ads. It's not like stuff on website where it's like 'watch this ad' or subscribe or whatever like that where you're actively frustrated with it."
We've been hearing very good things about the beta, so stay tuned. Ads or not.
