Cross-media productions: Using the same storyworld & digital assets for films AND games

Hi,
my team and I are working on a concept for the parallel creation of a film/tv production and a game, that are set in the same storyworld and share designs and digital assets. I was wondering if there are examples for this out there where these synergies were being used.
Is the idea even practicable?
→ If not, why?
→ If yes, does someone have examples or any other helpful info for me?

Thanks for your input!
Caroline
