David, it's the principle that they were promised this free content. Valve didn't deliver, they released a half finished game and made the other half a free dlc and were like 'Here aren't we awesome for giving you this!' when it's something we should of had from the beginning. We were promised free new campaigns, infected, weapons and instead they releasing a new game going back on their promise. Communities don't appreciated being lied to.
Anyway, I REALLY need to play with you some time >:U
