1984........ My favourite year for gaming. All of the best (imo) arcade games had been released by then. I bought my first proper games machine (Spectrum). All my mates owned various 8-bit computers. Good times.
One of the games featured on that clip is my all time favourite. 'Galaxian'. Not the abysmal home computer version shown there (which I actually bought back int he day, unfortunately), though, but the arcade game proper.
