$10/month, per user. Steeper than it sounds, unless the "user" is the indie dev and not all of the indie dev's app users... or is it each developer who works with the engine at the Indie dev shop? Not entirely clear in the article.

$10 per user per month would be nuts, you'd pass the full sticker price of even AAA titles in half a year, and makes no sense for 'one time cost' products, how long do you pay a monthly fee for? The lead in sentence is "indie developers will be able to use..." so I would interpret this as a "per designer/developer seat per month" license fee.

It's per dev.

It's really vague who the 'user' is, you're right. Am I paying them $10 for every copy of a game I ship?

Well then it wouldn't be "royalty free" :) - agreed the sentence is poorly written though. But yeah, it's per dev

I'm guessing it's something like Xamarin: https://store.xamarin.com/

(Albeit way cheaper)
