This reduced rate is meant to serve as an example to the wider community as to what a “reasonable” commission should look like. Now standard creators on ArtStation will see the same 12% commission rate found in Epic’s own Games Store for PCs, instead of the 30% it was before. One the same day as Fortnite maker Epic Games goes to trial with one of the biggest legal challenges to the App Store’s business model to date, it has simultaneously announced the acquisition of the artist portfolio community ArtStation - and immediately lowered the commissions on sales.
