When I was a youngster in the early 90s, a grade school classmate of mine had a huge computer network at home. His dad worked for the (local) Washington, DC NBC affiliate as one of their system engineers. Their house was fully networked mecca of multiple Unix, Windows, and Apple machines on different floors.
Back then most homes didn't have a computer, and if they did, it was just one. Internet connections were achieved with dial-up modems to the local BBS or service provider. Almost nobody my age was playing computer games, only people working in industry. Even fewer had a network, since online play didn't exist for most games (tho there were exceptions, like Netrek...miss that game too)
I originally learned the command line by using it to start computer games. This guy had basically ALL of the major gaming titles through about 1997, at which point I bought my own computer. Many of the other shooters back then were horror-themed knockoffs of Doom and Quake (like Hexen, Heretic, etc.), though all had their nuances. What I think of as the golden age of FPS games happened shortly after, in 98, with the release of Half-Life and Unreal.
That early experience was how I got into computing at a time when most kids had no real exposure to computers. Still miss those times.
