I understand your point. I just don't think that KF should do something just because L4D did it. Just cuz they did it doesn't make it okay. Making another game that is essentially the first just with updates and charging another 50 bucks for it is just wrong. Yes it is a great game, but sequels are supposed to be just that, sequels. not updates, sequels.
UT 2k4 was vastly different then UT 99, UT 3 was vastly different then UT 2k4. That is what a sequel is. Adding new content does not alone make a sequel. There is nothing in L4D2 that they couldn't of added to L4D1.
So if KF2 is made I want it to be vastly different yet have the same core gameplay.
No, TWI should do something because it makes millions of dollars. It has nothing to do with what Valve did with Left4Dead, it has to do with what brings TWI as a company money. The only way that a company makes money is by releasing product. Period. If TWI is not releasing content/product, they are not making money. Given the choice, I would much rather have product from TWI than I would not have product from TWI, and TWI not providing me more product.
The company will always make more money from releasing a new product with content that is extension of currently existing content than they will from not releasing new content for pay.
You, yourself, say "Making another game that is essentially the first just with updates and charging another $50 for it is just wrong." Not 7 sentences later you say, "So if KF2 was made I want it to be vastly different yet have the same core gameplay." Taken together with, "Adding new content does not alone make a sequel," I can only come to one inescapable conclusion.
You are an incredible idiot.
I don't mean that as a personal attack, I mean it as a straightforward analysis of what you actually said that you want. In summary, you said, "I want something just like I have only completely different, but not like Left4Dead2 was different; L4D2 only had an upgraded engine, new graphics, more weapons, and more maps." You do recognize how screamingly insane that is, right?
By your measure, games should never have a sequel -- any game close enough in concept to the original would, by your measure, be insufficiently different to be bothered making -- and any supplemental content, i.e. anything and everything, should be free.
There is no way that you can actually believe this and still think that there should be companies that will provide you games to play in the first place. So, either: (a) you don't actually believe this and you're lying, or (b) you actually do believe the mass of contradictions and insipidity that you're spouting. Neither of these two positions are particularly flattering for you.
I'm only putting this out there because, despite the smallness of the Killing Floor community which actually reads the forums (and we all know that the number of players that read online forums is miniscule compared to the total number of players that exist in the game environment), I see this argument come up in multiple communities all the time. It doesn't get any better from repetition. It's dumb. The more frequently and more consistently we can dispel this kind of ridiculous stupidity, the sooner we can actually discuss something that is meaningful and intelligible.
(TL;DR version: Who would you listen to if you ran a company, the guy that says, "I want you to give me stuff for free, and if you offer me more stuff sooner I won't pay for it," or the guy that says, "I can't wait to give you more money for stuff that I like"? It's a no-brainer. Don't be the first guy.)
