It's mildly alarming to contemplate how many years ago Ultimate Play The Game were ruling the ZX Spectrum gaming world. Jetpac, Knight Lore, Lunar Jetman: classics, every one.
That said, I'd completely forgotten about Atic Atac introducing the Chicken-o-meter to the world of gaming:
It's entirely possible to look at many of these videos and be amazed at how crude the graphics were, at how limited the gameplay was by modern standards. But consider that just a few years after the first generation of dedicated video consoles it was in the early/mid 1980s there were millions of households using cheap, mass market personal computers to play these games. If you were the right age in the early 1980s, these things were just plain miraculous!
