One game, by one man, on six platforms: The good, the bad and the ugly
If I had a time traveling magic wand, the one Software Thing I would wish for would be that native, cross platform toolkits had won the war rather than the whole industry punting and declaring The Web Browser to be the target platform, or these super-high-level Game Engines. For decades, I always hopelessly thought the OS and hardware gaps would eventually be bridged by something like Qt or SDL or wxWidgets, and we'd all one day be happily programming cross platform apps using plain old native languages and SDKs instead of Electron or the HTML/CSS/JS triad of pain. As the years go on, and OS vendors move even more towards their own proprietary incompatible native APIs, this dream seems less and less likely.
