One of my all-time favourite ways to waste time (I say “waste”, but see below) on a PC is X-COM: UFO Defense, a turn-based strategy game in which you act as the commander, or perhaps director, of a global agency whose job it is to prevent extraterrestials from successfully invading Earth. The gameplay is varied: some of the action takes place on a global, strategic level, where bases have to be built, squads equipped, and incoming UFOs intercepted; and some of it (most of it, during busy phases in the invasion) taking place on a more local, tactical level, where your squads need to be guided through close combat with the aliens, or your base itself defended from attack. Myself and a friend would play it together, conferring on the best way to manage the global situation, or on the most effective weapon for dealing with a particularly tough alien in a tense combat situation. Terror from the Deep, a sequel that took the action into the oceans, was equally immersive, if not more so, and also far tougher, as the invasion (or insurgency, in the case of the second game) intensified. This is a screenshot from the first game:

Lurking in the shadows in that image is a small and fast “little green man”-type alien (I’m sure we had different names for them, then), and I remember they were easy to kill, but very fast (although perhaps they weren’t even fast). The name of the character selected is one of the defaults given by the game, but all names were, I think, customisable, which led to further arguments (or maybe just debates) about how to christen newly recruited soldiers (Aliens, the James Cameron film, was a popular source as it contained many characters).
This screenshot is from Terror from the Deep, the sequel:

Daft name aside, you can see from that image that the weapon design shifted in a pleasingly (for some) retro direction for the second game, and also that the colour scheme used more sea-like yellows and greens and blues, something which many hated, but I really dug (it makes me think now of Stingray, and probably did then, too). I found Terror from the Deep more immersive than its predecessor because it was more difficult: I had to play it for longer if I wanted to win, and playing it for longer led to become more involved. But the first game is the classic, the one that blew everyone away.
Why am I writing about this now? A few nights ago I downloaded an XP version of X-COM: UFO Defense, and when I loaded it up I was suddenly sent back in time by the music accompanying the opening title sequence. I’m hoping to get a copy of Terror from the Deep, too, as I’m sure that too will bring back some memories of wasted (or well-applied: there may yet be an invasion) youth.
Right now, though, I need to track down some episodes of UFO, the television series starring Ed Bishop:

An episode or two of Captain Scarlet and the Mysterons wouldn’t go amiss, either:

And maybe also the “Mytharc” episodes of The X-Files:

You see, they’re all connected.
