Some assets might be a bit overpriced depending on the viewpoint, but they as in games might go on a sale when they dont make enough money for the developer.
Then again, some assets are way underpriced looking at what they deliver (for example im looking at you Generic shooter), but thats my opinion.
But yeah, comparing a relatively small demographic (unreal marketplace and its potential customers) against e.g steam userbase where one can actually sell thousands of copies of a single item isnt really fair in my opinion since the userbase cant really be compared due to sheer size difference.
Edit; and of course what i said had already been stated. Need more coffee…
Edit no2; Its kinda funny and sad at the same time, that nowadays when we have the internet and all the tech and entertainment available to almost anyone people arent that willing to pay for other peoples hard work since the whole market is so saturated with stuff but still feel “entitled” to the same level of quality.
Lets take music for example, since now theres spotify etc, who here is actually willing to pay 20bucks for a cd?
Or hire a professional photographer to capture those significant moments in life due to dslr kits are relatively cheap and someone in the family has one?
Not many.
I might just be rambling incoherently and comparing apples to bridges but i hope i made some sense
