According to this Shacknews piece, id revealed at QuakeCon today that the firm was forced to change the name of upcoming free-to-play shooter Quake Live from the original Quake Zero because of a domain squatter.
Apparently the company announced the game without registering the domain. Sensible.
“This was an idea we had mere weeks before QuakeCon ,” said Carmack, emphasizing the speedy nature of the game’s confirmation.
An enterprising individual captialised on id’s lack of plan, but Carmack was having none of it.
“They offered us a considered buyout option for it,” he said. “We just decided heck, we’re only a few months into development of this, we’ll just change the name.”
