In Insomniac’s leaks a couple of years ago, the licensing of the Marvel IP (e.g., Spider-Man, Wolverine) went by a net revenue share agreement running at 10-20% on digital base copies. For DLCs/add-ons, the license fee increased to, if I recall correctly, about 20-25% of net sales.
I would think LEGO could go with similar terms, given it’s a big, well-known, attractive IP. This is purely speculation, of course. However, I don’t believe a single cent flows from LEGO towards Paradox.
