So, I'm taking from this that the moral is to always do your best work no matter if you think it's a just a toy or if you actually want to sell it. Sometimes toys accidentally become products.
Uh, not to discourage anyone or anything.
Al Lowe gave that interview a little while back and it showed up here on HN. He said he was a little sad that people didn't make funny games any more. Well, sometimes they do, and it turns out, people are willing to buy them.
A friend made a platformer for an incubator called "Runnin' Around With No Shirt On" where it's basically about a (shirtless) guy running around in hell (and dodging all the basic platform obstacles like spikes, moving platforms, etc.). The goal of the game was to defeat Satan in order to get his shirt back.
It was the most ridiculous thing I've ever played but I couldn't go one second without laughing at how ridiculous and how much fun it was to play.
I love "serious" kinds of play and games with these awesome narratives but sometimes you just want something funny and fun to play!
