It's extremely telling that nobody (developer or consumer) takes the Epic Games store seriously, in spite of their effort to undercut Steam on this front (0% on the first mil, and 12% after that - to say nothing of the free game promos.)
I could be wrong, I don't keep up with Epic because the store itself has such bad UI design.
(Granted, Steam isn't too picky either, but at least they draw the line at unregulated speculative assets.)
