It's most likely around 30% which seems to be the norm for stores like this

Epic’s store is 12%. Tim Sweeney tweeted that Epic take 5% as profit and the rest are costs[1].

Puts the other stores’ 30% in context, though Xbox/Playstation/Nintendo do significantly more QA than Epic.

Also, physical retail distribution is likely around the same 30% ballpark.

And is why Apple chose 30% when they launched the app store; it was already an acceptable charge, and could be justified with storage/bandwidth costs and the suite of tools/services built for it.

That doesn't seem to line up in my books, but we'll see how the next few years go while the 30% commission standard still has a target on its back.

For a console game you'd have to pay a 10-20% title fee and then the retailer also takes 30-40%.
