My dad used to. He introduced me to a ton of video games when I was a kid, buying me an NES and a Genesis, plus installing all sorts of games in his old Intel 386 for both of us to play. When he started using a Mac (with the old pre-OS X operating system) we played 1v1 Marathon together a lot. He later got back to Windows and was the person to introduce me to such landmark titles as Deus Ex and Far Cry while I was spending my time with JRPGs in the Playstation.
After he remarried and had my little sister (and later my little brother), it was very difficult for him to keep up with games. He's shown a little interest as of late, but alas I don't live home anymore so I'm not there to help guide him.
