I also preferred first person shooter which was ruined with the addition of the
barely controllable npc as 'allies'.
Although, thirty years I liked the RPG games. I’ve taken a preference for strategy games, like Civ 3.
A good site to download older games is www.gog.com.
You can download most pc games there and bypass the upcoming subscription model altogether.
My kids were playing some of the early versions of Doom. I put Ethernet cards in their PCs so they could engage in multi-player mode. Strictly on our home LAN. I spiced it up by patching some of the characters to be pink rabbits. It was amusing for them in the late 80s. My "gaming" had been limited to the early versions of "adventure" with strictly keyboard entry and text responses. Mapping the caves was done on a local piece of paper. There was no graphic to spoil the task of building a mental model of the cave structures. When games devolved into full graphics with game controllers, all the imagination/logic went down the toilet.
