There was that brief moment a couple of years ago when it seemed like maybe, just maybe, with original developer Bungie parting ways, the Halo series could be coming to an end. Then reality (and its accompanying scads of cash bags) sank in. Microsoft is surely happy to have kept the saga of Master Chief and Co. going, as Halo 4 ($60, Xbox 360) raked in a whopping $220 million worldwide in its first 24 hours. Even if the campaign mode has its cheesy moments, you can always count on a superbly crafted multiplayer experience. And Microsoft can count on a blockbuster.
