And we now conclude our groundbreaking documentary chronicling the games that made the 20th century

Missile Command - shoot 'em up (Atari)
Released during a time when nuclear war still walked hand in hand with such cheery fears as rape and murder. Missile Command effortlessly trivialised nuclear apocalypse. And it was fun, too. While researching this feature, a thought suddenly occurred to us: which came first? Missile Command or President Reagan's ludicrous, so-called 'Star Wars' nuclear deterrent proposal? And on that terrifying note...

Bubble Bobble - platform game (Taito)
Fat dinosaurs encase their foes in bubbles. Said spheres are then exploded by means of horn, or spike. By way of acknowledgement and reward, fruit appears. And on it goes, with scant respite, single screen after single screen. Play with two, play with one; great regardless. Classic. Brilliant. Magnificently playable. Bubble Bobble always was, and always will be, ace.

Tempest - shoot-'em-up (Atari)
The Marmite of the videogame world, Tempest inspires a lust-like fervour in some gamers. Others, by contrast, regard it as an interesting, but lifeless relic of a bygone era. It was definitely influential, but it's hard to pinpoint in which respects; it's a classic that just is.

Kung Fu Master - beat-'em-up (Taito)
We can still, to this day, hum the soundtrack to this to the very last note.

The Sentinel - puzzle game (Geoff Crammond)
With development costs perpetually on the rise, and between six months and four years to make a videogame these days, why would programmers or their employers wish to spend that time with a 'nice idea' that probably won't sell? The Sentinel would not be made these days, we fear; it is fortuitous that Geoff Crammond had his flash of inspiration back then. Parked in a lay-by between boardgame and videogame, it's a beautifully simple design - and, lest we forget, a visionary piece of programming, too.
