Left 4 Dead 2 has been announced for a release in November, less than a year after the original. Is this an odd choice? Sure it is. Is it a BAD choice? That's debatable. Did the announcement make you ANGRY? Now you've gone too far!
Obviously, people are pretty angry about this. But WHY? You have your knitpicks, your dislikes, and you wish they didn't release it so soon. But it isn't like Valve is FORCING you to buy it! If you don't like it, then just don't get it! It's that simple! Stick with the original L4D.
