Most games seem to. It’s just that most games don’t get a lot of play out of it. As most TV, Movies and books don’t. There’s a dollar store some where with a bin full of Terra Firma figures. And I’m pretty sure you can get a sexy anime maquette featuring Candy Crush. And there are whole, complex continuities of licensed books and pen and paper games for some unexpected shit. Practically everything but indy games these days gets a licensed comic.
Games are a bit behind on this though. For blockbuster movies and certain types of TV there’s often more money in merch and ancillary stuff than the movie itself.
For all the money something like the Avengers makes there’s billions more in t-shirts, toys, officially licensed toasters.
Games outside of some exceptions it seems to be a little bonus. But some of the exceptions are unexpected. Dishonored has a huge ancillary presence that seems fairly invisible till you run across a fan wiki.
