Gamasutra - Modern Warfare 2's Singleplayer, Multiplayer Conundrum. Thanks Joker961.
The game’s science fiction storyline, bad writing, and spotty pacing are enough to tarnish it in my memory, but it commits many more errors within the mechanics of the game itself. Still, the multiplayer is incredible: Infinity Ward is so close to creating an incredibly addictive MMOFPS; another development cycle or two should do it. What’s alarming about Modern Warfare 2 is that Infinity Ward seems dead set on inflicting their bad brand of single player FPS upon us for years to come. If they moved on to a different franchise and genre (as they may be doing), they’ll take their overblown sense of drama, amazing design experience, and broken sense of gameplay narrative and pacing, and slip it into another game. They make single player (portions of) games that “push the envelope” of design in only the most superficial of ways, and they set the standard for the rest of the industry.
