And that is why, much like with any field, the stuff you learn in 100 level courses is just enough to make you an example of the dunning kruger effect in action.

Simply put: The supply/demand curves and what not only make sense with fairly small markets. Once you have a larger consumerbase, that gets a LOT more complicated.

Think of it like this: Maybe in Flushing Meadows, people will pay a 75 cents for a glass of lemonade. And on 4th street in Detroit, they will pay 5 cents (and may just mug you anyway, because Detroit). Do you price for 4th street and lose out on 70 cents per glass in Flushing Meadows? Do you just write off Detroit? Or do you have multiple prices?

That is why most games follow the 60->40->30->20 model. You get those initial 60 dollar sales from the people who will pay full price, and then a month or two later you drop to 40 so those folks' friends will buy in. When the next spending-heavy holiday comes around, you go to 30 so people will buy because they heard good things. And then you leave it at 20 until the end of time because that tends to work well for a bargain purchase. Add in quick discounts, and you manage to get almost the entirety of the money under that curve.

Same thing here. You would rather get something than nothing, so you offer the poor souls of Detroit cheap lemonade, but you don't want to lose out on that Flushing Meadows cash. And if someone from Flushing Meadows takes a plane to Detroit: Let them, they aren't worth the hassle (and maybe they'll get mugged and "learn their lesson"). But if all of Flushing Meadows starts doing that, you find ways to keep charging them that 75 cents (DRM).
