Who knows? The future market is going to be different from the current market.
The future market will incitate to use mods.
In the current market, modding serves the purpose of satisfying an unexpected demand: players who buy products they know to include disliked features.
Modding allows to remove the features.
In the current market, the need for mods is untangible, games at release usually do not call for mods as mods are pressed by a matter of tastes.
These days, though, the PC scene is less and less about gaming, more and more about money. PC players want to make money off playing video products, be it by modding, streaming, playing monetized competition etc
Modding currently does not serve this purpose. Contrary to one claim made above, devs must release control over their products to make room for the modding scene expression in a compulsory way.
In the future, games will be released to call for mods. One possibility is to switch from modding as a matter of tastes to modding as a matter of utility.
The PC scene have been cheered up for crowdfunding and crowdfunding is about releasing faulty products on purpose.
Others devs are going to follow suit: this will make room to modders to sell their mods in a compulsory way.
One example: Cities Skyline.
It is standard to distinguish between similar things by using different colours.
Lines in a chart are displayed in different colours. It is a matter of utility.
Video games including charts integrate the standard.
On release, though, CS did not include the standard: transportation lines, when created, all displayed the same colour and were hard to distinguish one from another. This could be corrected manually (a hassle)
Compared to the record of the dev company (Kollosal order), the product was released faulty as their previous products included the feature of automatic attribution of a different colour.
The solution to this miss in utility? The modding scene. Quickly, a mod to attribute automatically colours was released.
This kind of modding is not tasteful modding, it is useful modding.
Not buying a taste based mod? Maybe.
Not buying a utility based mode? Maybe not.
This kind of modding serves the purpose of satisfying PC players who want to sit at their desk and make money off playing video products.
Both sides profit.
Devs can sell their products to a higher price (this kind of utility mods are going to be cheap, it might take ten or so to meet the standard in utility formely provided)
PC players get what they desire: room to make money off video products.
Today, products do not call for mods.
In the future, products will call for mods.
By the way, one measure of the devs' success to provide what the PC scene desire is the devs' capacity to make the use of mods compulsory.
In the future, products that could be used without mods will be bad products.
Products that could not will be good products.
In these conditions, who knows what he is going to buy?
