Gamers With Jobs writes: "The very best games deliver powerful experiences within clearly defined and believable contexts. In the case of Left 4 Dead, Valve's zombie-shooter, context is so important, it nearly overshadows the game.
Left 4 Dead begins with the best produced and most relevant opening cinematic I can recall. Yes, it is well written, animated, directed and voiced. But much more important than that, it immediately took my preconception about the game as just a co-op zombie shooter and gave it just a shove. "The game you are about to play," it implies, 'is not a zombie game. It's a zombie movie simulator.'"
