I think the price is fair from a labour point of view, however, I feel like there may be an issue of offer and demand.
If you are not doing a specific commission (someone asked for it) who is going to buy it? I don't see many people spending that much money on an utilitarian object where the art, for how nice it is, isn't going to add much.
You may find someone for which money is not an issue and want something "extravagant" on display in their office, like a lawyer or a doctor. But I think is a small niche.
This also taking into consideration how sturdy the piece is. A regular folder can get damaged pretty quickly, which may put people off from buying it. Which may be doubly so if the art could get scratched or is unprotected.
Yes, the headline feels very disingenuous. They are working with composers from those games... I don't feel they are going to have the same influence some game designers would have had.
