After reading a few comments that brushed on the topic, I realized that all of the assets in the Asset Portal are free. Monetization is sometimes there through donations on PayPal or something similar, however I’m not aware of any Lua modules or other Defold-specific assets that cost.
I’m thinking about gunnie-pigging this idea. I don’t believe paid assets have inherent value simply by including a price tag, however I do believe they have potential to be more reliable, specifically in quality and maintenance. Why? Because when developers are paid to make and maintain high-quality stuff, it’s easier to justify making and maintaining high-quality stuff. Paid assets also come with a reputational implication. Why? Because free and open-source software is under no obligation to be professionally written or maintained, however there is that inherent expectation for paid software. (This is debatable and nuanced, of course.)
Does the Defold team or anybody with relevant experience have advice or guidance on how to go about this? A paid asset wouldn’t be freely available on GitHub, obviously. Not exactly sure how I would distribute the code to work with Defold’s dependency system.
