How did Quest for Camelot end up on this service? It's based on a movie so presumably there are some publishing rights issues involved here. So who goes and obtains the permissions from Warner Bros to re-release a videogame that's over 20 years old that was never very popular that is based on a movie that wasn't very popular? And this isn't a storefront for individual sales, this is for a subscription based service. No one is going to sign up for the service for this game but presumably Nintendo will have to give Warner Bros some sort of payment for it. Doesn't make business sense to jump through this many hoops unless the game itself has a big fanbase like Goldeneye or the old Ninja Turles games.
The only angle I can see is that since Nintendo co-developed it that maybe they will lose some copyright claim or something like that if the game is out-of-print for too long. Or I wonder if Warner Bros now owns the game and is trying to get figured into Nintendo Switch Online and this is one of the only titles they could offer.
