I wonder if this effect applies to games too? I sell games and unfortunately I don't think it does. I would love to be proven wrong however.
1. Few gamers make a living out of doing it.
2. There is a much wider selection in the number of video games they can choose to play.
So you have two forces working against you. First, if you raise your prices, there are a lot of other games people can play. Second, if you raise your prices, people can simply choose not to play at all.
Not so with audio engineers. They must have the software to make a living, giving them a lot less choice in the matter. They also probably become more intimately familiar with the software than most gamers become with video games. Finally, the context encourages a level of maturity that recognizes the impact of freeloading and fosters good-customership.
So, that's why you probably won't be able to charge more for a video game. Although they do get away with it in some contexts (rock band, some racing games).
P.S. as much as you would like to believe gamers will pay for quality wherever they find it, there's also this issue that in your industry (apparently roguelike games) there's this huge norming influence toward free-to-play games. That probably doesn't help you much.
Frustrating, to say the least. $15/mo for (in many cases) 60-80 hours of entertainment per month, if not more for the extremely hardcore.
Gaming isn't really the same field as commercial software; a product is released once, and that's the end of it, as opposed to needing long-term support like a commercial product does. Put another way: after people buy Halo 3, they aren't likely to upgrade to Halo 3.11 for Workgroups.
