When these new stores come into being in Europe it will not create competition. If you want fortnite you will only be able to get it from the epic store (not a steam store, or an amazon store) and it will be the one price. It's not like a packet of oreos where in one store it might be less than another diving prices down.
Think. Think!
Again, let's look at Mac, which is basically a good proxy for how this already works. Are there apps in the Apple App Store that are also sold direct by developers too? Yes...
many! So why would a developer able to sell direct- which is ALL of them on Mac- opt to also put their app in the Apple Mac App Store too and give Apple their big cut? Because they can sell more units by being in
both places even if those who buy in the Mac App Store will have a cut of those extra sales staying with Apple.
Are there any apps that are sold on the Mac App Store, on the developers own store and in other stores and in bundles too? Yes. Why? Because even wider distribution will make some extra money for developer that they may not get by making sales only available from their own store... even if sales on their own store maximizes their own revenue & profit for sales of that app. Less profit is better than no profit in those other stores/channels.
This will be the same.
Besides, there is some portion of EU Apple people who will be snowed into believing the nonsense we've all been slinging about third party app stores delivering apps loaded with virus, trojans, plague, pestilence, venomous creatures and soul-swiping demons. So a developer pulling their own app out of the most trustworthy store that people
already know and are accustomed to doing their app business with would be shooting themselves in the foot.
Will some developers pull their apps and only sell them in their own store? Probably. And if they do so and see their overall revenue go down, they'll learn a
different lesson in the most tangible of ways and get their app back into the Apple App Store too.
If I was a developer, I'd both sell my apps direct and get them in as many profitable distribution channels as possible so I could reach the maximum number of buyers. Yes, I'd make maximum profit by direct sales but I may make maximum revenue (but less profit) by selling through a bigger store, other stores and/or in app bundles, etc. And even if I take some hits by also selling in those other channels for
this version of my app, I'll establish a relationship with those buyers so that next time perhaps some of them will opt to buy version "next" direct from me and I'll make a bit more money then.
This is how it
already works on the Mac App Store. It will be the
same here.
