That lasted long. John Romero and Adrian Carmack, founders of the Doom and Quake developer iD Software, have already pulled the plug on their new Kickstarter project. The Blackroom campaign had been running for four days when the pair decided to press "pause," citing the need to make a gameplay demo. That's most likely so that their new, rebooted campaign can adhere to Kickstarter's own rules, which require "explicit demos of working prototypes" for any proposed physical product. The pair say finishing an early slice of Blackroom will take longer than the current campaign, which is why they've decided to end it so prematurely.
