I recall my dad bought a book with VIC 20 games printed. And you bet I typed them all in. And then had to debug them.

It wasn’t this one but it was very similar: https://archive.org/details/games-for-your-vic-20/page/28/mode/1up

And this book came with the computer and taught me how to code: https://archive.org/details/VIC-20_An_Introduction_to_BASIC_Part_1/mode/1up

Such fun memories. And now I’m CEO of a software company haha.
