Kinda both? It is a proprietary engine with a license deal that seems fair to me. It is a fair trade-off instead of making my own engine.

>What do I need to do when releasing a product?
>You must notify Epic when you begin collecting revenue or ship your product; see here for more details.
>If I release a commercial product, what royalties are due to Epic, and when?
>Generally, you are obligated to pay to Epic 5% of all gross revenue after the first $3,000 per game or application per calendar quarter, regardless of what company collects the revenue. For example, if your product earns $10 from sales on the App Store, the royalty due is $0.50 (5% of $10), even though you would receive roughly $7 from Apple after they deduct their distribution fee of roughly $3 (30% of $10).
>Royalty payments are due 45 days after the close of each calendar quarter. Along with the payment, you must send a royalty report on a per-product basis. For more information, see here.
