I love this sentiment, and it can be true, but it also creates this idea that 'heart' alone has a high bearing on whether or not a product of any kind (book, film, statue, game) will be successful in its market ambitions.

It doesn't always correlate. I would argue if often doesn't correlate. Any indie film or game fest is chock full of projects with a ton of heart. Few of them graduate to success in the market place.

I'm not saying heart is a bad thing. It's a damn great thing. But strong business fundamentals are a good thing too. And sometimes, you also just need that extra bit of luck or uncontrollable virality too. To find success, you stack the deck with as many good plays as you can, and heart is one of them.

Success is not a recipe, and if it was, everybody would be doing it...
