What I love most about BASIC, and makes me nostalgic for my old TRS-80, is visible in the article.
All the games show graphics. Because writing graphics and taking unbuffered input, is simple and easy in BASIC.
It took me a week, with nothing but an idea and a language manual, to write a primitive Pacman.
Today, I'm not sure if I could write such an easy graphical program without diving into some sort of graphics framework, struggle to find the right language bindings, and get frustrated with the framework not matching patterns common to the language.
There are few languages today that make it so easy to unleash creativity.
