Do you think that a game would earn more money by launching at say $30 instead of $50? Has any publisher tried that experiment?
Possibly but that ignores a simple economic fact.
At any given price point there are likely to be people interested in buying that.
So...
...at 150 USD there's W amount of people
...at 100 USD there's X (which includes all of the above) amount of people
...at 50 USD there's Y (which includes all of the above) amount of people
...at 25 USD there's Z (which includes all of the above) amount of people
If you sell at 25 USD, you're likely to not make as much money as if you sold at 50 USD and then in a few months sold it at 25 USD.
It's quite possible that you could make more money by selling it intially at 100 USD, then 50, then 25. But at 100 USD you may not get enough purchasers to keep your company afloat for very long.
In the past, the fixed cost of physical media, packaging, shipping and handling, and retailer inventory meant you couldn't quickly address changes in buying habits.
Steam and digital distribution in general, allow a developer (if they so choose) to quickly reduce prices once the people willing to pay 50 or 60 USD becomes a trickle. They can then easily go to 20% off or 25% off. Eventually going all the way down to 66-75% off. Perhaps even 90% off eventually.
By the time they get to the 66-75% off range, chances are they've made their developement costs back already and now it's mostly profit. At the full price of 50 or 60 USD they are likely still recouping development costs for your average title, while blockbusters will likely recoup all costs during that initial buying frenzy. Average and little advertised products may not start to make a profit until the 20-50% off phase.
If they all started at a lower price that just means it'll take that much longer before they recoup their initial investment and start making a profit. And if they run out of potential buyers, the original developers may never see a dime as the publishers keep reducing the price to try to get new buyers in an attempt to recoup their initial advance to the developers to make the title in the first place.
