This is the core of it, but there's a very simple reality concerning any sort of sale that will never change:
It's up to the consumer to decide the value of something for themselves and whether or not they want to spend money on it.
That's the ultimate consideration that determines whether something will or will not sell. No one can "force" a consumer to buy a game they don't want to buy. No one can be "manipulated" to do anything if they're making educated purchases. Value cannot be "dictated" from the outside. In the end, if people do not want something, they will place very little value on it, and no one will purchase it. Conversely, if something is viewed as valuable, then it will sell, even if it holds no practical value.
Supply and demand. That's all it is.
Yeppers. A customer may be naive to pay up front for an unrealized product. They arguably shouldn't have to worry about getting boned from all directions in the first place though. I view these as two separate issues. On the one hand you got companies trying to bone customers from all directions. On the other you got customers falling right into it. The latter doesn't exist unless the former does. Thus, the former is the root cause.
Yes, it could be viewed (subjectively) as "exploitation" of the consumer base, but that's the heart and soul of capitalism.
I don't consider pre-orders, early access, etc. as exploitative. I do consider offering pre-orders, raking in money, slapping mission acomplished on it and deliberately dragging feet instead of providing a quality product as exploitative. For clarification, by exploitative I mean the most negative connotation of the word (abusive is probably a better word).
I would disagree with the notion this second one is inherent to Capitalism. Capitalism is an economic system, nothing more or less. It's not inherently "bad". It only becomes inherently "bad" when people choose to wield it as such. Most systems employed by people have a similar issue (system is designed fine, then some dipshit gets a bright idea to abuse it).
And, at all times, we have total control over what we spend our money on. Educated purchases.
Yeppers again. The irony is the customers hold all the power when it comes to a lot of entertainment.
Unfortunately, modern day one universally has to assume anything being sold has a catch to make educated purchases. It's on sale. What's wrong with it? It's a 2 for 1. Which one is broke? It's 50% off. Then why is the base price twice as much? We spent more money on marketing the product instead of building it. Alert, alert, red flag detected.
I don't know if you remember but in the past every game was releasing a DEMO you could download for free and play it.
Just imagine if video game marketing never showed features until they were fully complete and in the game and work in progress wasn't usable.
Times are changing but you still can wait for reviews and more "honest" videos to asses if the product worth your money.
You can but out of every 10 reviews it's a good bet 9 of them are not of the honest variety. Especially if it's from the "mainstream" sources.
