I'd say all of them (except maybe rock opera). See for me, it isn't just ONE story. It's multiple stories with multiple characters and their supporting cast. I feel it'd be easier for a film director, video game developer, animator to pick and choose what character from my comics universe they want to adapt in another form of media. In fact, my goal is to one day become an animator and adapt my comics universe's staple characters, (the character or characters you associate the most when thinking of a franchise like for Marvel, you think Spider-Man) The Action Fruit Society, into an action adventure show.
