As these are based of the films as much as the books I think they probably have a favorable licensing deal compared with the other licensed Traveller’s Tales Lego games.

The other franchise that might compete is Lego Batman but for that the one the series was released between 2008 and 2018 (i.e. spanning PS2, PS3, and PS4) and it would take a full rebuild of the earlier titles to bring them up to a consistent standard. Probably more effort than they want to spend on a cheap cash grab.
