Thank you for your response. I know open source games aren't the norm, but they do exist and are something to be encouraged and discovered. For example, consider Quadrilateral Cowboy[0], which is a recent game made available on all platforms, for sale on Steam, and open source. In particular for SHENZHEN I/O, this is a game all about coding! It's seem reasonable to consider that it might be open source and if not, to want strongly for it as a natural extension of the game and so to wonder what similar games exist that are modifiable. Regardless, I do disagree with discouraging discussion around open source software, original or alternative, commercial or otherwise, and was a little saddened to be downvoted for it on Hacker News. I appreciate your civility and consideration.
