I understand your views Jon, and I agree that there's no real weight behind any of the arguments made by the 'anti left 4 dead 2'. In fact, I think that the main reason complainers are just hardcore elitists.
That said, in my honest opinion, I don't think that L4D2 is worth the price tag they have put on it. We can argue about this all day long but I'd rather not since it would derail the thread so I'll just chuck this stuff down and accept whatever you guys say.
From what I've seen of L4D2, it looks a lot like L4D but with a few little addons and the like. Really, the characters look like they just reskinned the originals (and TBH, the new characters don't have the same feel), the atmosphere is done thanks to bright sunny daylight and hillbilly music and the gameplay looks to be pretty much the same thing again.
That said, there are a few things I like about it. Primarily the new 'gauntlet' crescendos and the improved AID. Even so, in my mind, that doesn't justify me spending the money on it, however if anyone else wants to I won't stop them or judge them on it.
In the end I believe that the outrage from the elitists is because they bought the game and were told they would get new content. That, in their mind means that the developer is supposed to dedicate themselves to it for a while. Which, as you said, is entirely untrue, but nonetheless, when a developer says that they will continue releasing new content, coming up and saying that the fans have to pay for a new game less than a year after is bound to make them lose a few people.
Yanlin: I agree, L4D was, and is still epic. But I think the underlying problem with L4D2 in a lot of people's minds is that it is essentially still just L4D but with a few little bells and whistles added on.
G-Flex: Again, I agree there, they can be criticized for the way they handled this (people were already getting peeved because of the constant survival pack delays, then when it came out, it was glitch filled and by the time everything was fixed, people were finished with it). That said, it is like Jon explained, you buy a game because of the already included content, not because of what you're expecting to be added.
