Despite their best happy-enthused-marketing-face, I think it's fairly safe to say most people have been left cold by Microsoft's Games for Windows Live! strategy. I think...pointless is the word that best sums it up. Infinity Ward, who are currently sweating away on Call of Duty 4, are of a similar opinion. When asked by IGN about their thoughts on the service, studio head Grant Collier says bluntly:

Our rep left us a message saying 'hey, want to talk about this, Live Anywhere, it's big, it's cool', and I thought, well yeah, if you're playing online poker, but who wants to be playing an RTS on a console and have some guy on a PC clicking and dragging all his troops, attacking your base while you're sitting there with your thumb sticks. So I think for FPSs and RTSs, no way, but for, y'know, card games or Tetris or something like that. There are games that I think it's cool for, but there are other games where I don't think there's any point. So they just didn't respond.

Card games or Tetris? Ouch. Snap, even. Luke Plunkett
