In an interview with Infinity Ward's studio head Grant Collier, IGN discussed everything Call of Duty 4 and got the company's opinion on Microsoft's Live Anywhere initiative. Grant said that after Microsoft pitched the idea of incorporating Live Anywhere into their games they felt that it wouldn't work with their projects and simply said "no way". Collier says such a system is best suited for "card games or Tetris or something like that" and not the RTS or FPS genres. Microsoft didn't have a convincing argument to Infinity Ward's complaints and didn't respond to them.
