I’ll go first.
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, a sim/strategy game which I didn’t really get as a kid. Now that I’ve gotten into strategy games like Civilization and Romance of the Three Kingdoms it would be interesting to revisit.
We had a TI-99/4A as well. Munchman was a Pac-Man clone that we loved and A-Maze-Ing which was a simple but fun maze game.
After that we had Socrates which was a cheap edutainment console thing with built in games. I don’t remember the games but it was lacking compared to the TI.
