We’re coming up on 50 years for Space Invaders. We can say that it’s endured because:

- it’s self-contained: it works without dependencies, and with the hardware it was designed for

- there’s an ongoing need: peope want to continue playing Space Invaders

- it’s transposable: the environment it runs in can be recreated through additional layers (emulators here)

- it’s recreatable: the core concepts behind Space Invaders can be reimplemented in the prevailing contexts of the time
