When I was a kid my family had a TI-99/4A. The 99 series was Texas Instruments’ only real foray into the PC and video game market, and it failed to be competitive with Commodore, Atari, and Amiga. Most games were booted from cartridges. My favorites were Hunt the Wumpus, a sort of early survival-horror with a turn-based grid system, and Alpiner, a mountain-climbing game with various hazards, kind of a reverse SkiFree. It also had the ability to read data from cassette tapes to load text-based games. The one I remember is Hammurabi, which now that I’ve gotten into strategy games like Civilization and Romance of the Three Kingdoms would be interesting to revisit.
I played “Advanced Dungeons & Dragons” on the Intellivision that my g/f had at the time. Most everyone else had Atari 2600s, so it felt rare (at the time) to play on it. It had a funky controller with weird keypads and a disc that was like a joystick, but hard to play with.
