When Left 4 Dead 2 was first announced a scant few months after the first as a full on standalone sequel, it caused more than a few gamers to feel a bit pissed. After all, hardly any of the promised expansion content for the first had yet come out, and many didn't initially feel that the game sounded like enough of a sequel to warrant another full purchase price. Some new maps and new character models, big deal right? Thankfully, those misgivings were unfounded; Left 4 Dead 2 is the same core gameplay as the original title, only expanded or outright changed, in many areas. In a sense, not only is the game a fully qualified sequel, but it makes the original obsolete in almost every sense.
