Imagine how cool it would be if old games were distributed in source code form, so that anyone can modify and "remix" it as much as they want with a simple text editor?

This was impossible back in 1990s, but today we can get a C compiler (tcc) which takes less than 1 megabyte of space and compiles+links a game in less than a second. As long as you don't depend on too many third-party libraries, you can ship C code, compile the game on each start and user won't even notice!
