I guess Gackt's P.S I love u app is a bit like that. As a huge Gackt fan I got bored of it pretty quickly. There was so few options to choose from, you just had to read a story with a heroine that's meant to be you, but does nothing you'd actually do. (Like turning down her best friend for the Doctor who barely looks at her).

It's a nice story, but it's not a game.
