Although the irony is that in making tools (I’m a publisher as well) the bulk of your customers will be from this segment. In general though I think that Unity statement is a net positive but like anything else you have to take the good with the bad. While like any other profession (music, making movies, etc.) most will try and fail because nothing is as easy as it looks, there will be those that persevere and make something great. There will be some that feel entitled and complain on why is this so hard, or I want my money back, etc. but they are the minority just like those that make it big are in the minority.

I really think that as far as a marketplace refund policy goes, Epic should really adopt the Unity one but they’d have to improve their website/publisher portal to support some of those features (invoice checking, telling whether the product has been downloaded, etc.). Although as a customer on the Unreal Marketplace I do have to agree that the descriptions on average should be better and more publishers should get into the habit of providing a demo, or at the very least have some meat in their screenshots and/or videos (not commenting on specific products just a comment on the average). Then there would be little reason for as a customer not knowing what you are getting so you can make the return policy a little more strict like the Unity one.
