summer of 1979, I played Star Trek on an Apple II
Around 1974 or '75, played it on an ASR33 over a 110 baud acoustic-coupler modem to a PDP11-45
'75 or '76 played Hunt the Wumpus on a visit somewhere (don't remember where), liked it, decided to write my own version for that 11-45 in DEC's Basic-plus, but I hadn't noticed the map was that of a dodecahedron, so coded mine for a random map with guaranteed connectivity. One gameplay, I started in a sort of polyp on the map of a few connected caves with a single connection to the main cave system, unfortunately through the bottomless pit so I couldn't get anywhere near the wumpus. Luckily there were bats in one cave of the polyp, so I could get moved to somewhere random which happened to be in the main cave system.
My favourite game of that era was advent (Colossal Cave) on that 11-45 or the 11-70 that replaced it; there were effectively no home computers at that time, so I didn't get to play much, only when I walked the 5-6mi to my father's workplace (and a couple of times that and more back home, as I'd missed him). In 6th form (HS upper class), the only programmable device available was a Busicom calculator, programmed by a punched card which was driven back and forth through the reader (if you needed a longer programme, you had to tape cards together). It had a vector-driven CRT showing the handful of 20-digit fixed-point registers and memories in 7-segment form, and used folded mercury-column acoustic delay lines for memory. I don't know if it used the 4004 or was from just before microprocessors, probably the latter, and I can't now find anything mentioning it. My HP33E (a graduation present) easily outperformed it.
After starting to earn enough to splash out on a computer, I got the BBC model B (this was pre-PC), and the classic 'Elite', eventually reaching Elite status, then started again with a constructed profile with no money, cargo or weapons, playing until I'd well past the original starting state (headbutting asteroids for the 0.5 credit bounty to begin with). One of the interesting things was reverse-engineering the copy protection to be able to make a backup copy, which meant I had to write my own disk unformatter; another was my home-made analogue joystick without centring springs (just my added centre detent), which meant it was fairly easy for me to line up on a newly-appeared ship, ready to zap it if it started firing (a pirate).
