Sorry, I should have qualified that by saying 'successfully'. As in people pay for your content. Anyone can post text.
I am unsurprised that in a straight female protagonist game people are not automatically interested in your "age difference" gay stories.
That's not to say you couldn't make a game like this, like
Girl Spy. But you didn't. I played that. Wasn't for me but I thought it was pretty good!
Try it. If people hate on you for trying to make your game I would absolutely hate on them harder than you hate on this game.
