It doesn't solely have to be an adaptation either. Tie-ins are often universe extensions, such as when books are written in a pre-existing movie/show/game universe.
Often, media tie-ins are seen as soulless marketing cash-ins (which is sometimes accurate), but others are legitimately great in their own right.
What are the ones that you like and would recommend? What makes them noteworthy?
Meta note: Feel free to interpret this criteria as broadly as possible. This isn't about splitting hairs about what "counts" as a tie-in, but more about exploring things that have done a good job at jumping between media types. If you've got a Teenage Mutant Ninja Turtles watch that you love, that counts! Same for that Death Stranding fanfic you can't get enough of.
