Hence why you release a new product. You can’t indefinitely make income from one thing until the end of time.
You can charge more for a new product, as you can actually scale for inflation when you have to make it from the ground up. After all, the tools and manpower it required cost more now. So you can charge more.
But asking for more money for a product that was made half a decade prior, that didn’t cost what it costs now since inflation wasn’t where it is now, isn’t the answer.
Listen, as a general rule of thumb, if even EA and Activision won’t go there, maybe you shouldn’t either.
