I used to ... when I was younger. Played D&D in the 80's along with Middle Earth, Rolemaster, Runequest. Call of Cthulhu, Star Trek, Maelstrom. Warhammer, Dragon Warriors, Tunnels & Trolls, Judge Dredd, Conan ... ok the list goes on.
The top and bottom of it is when the CRPG came into being I drifted off towards the single player game and never really went back.
