My dad dabbled in gaming from time to time while I was growing up. In the early 90s he'd play the occasional game of Blades of Steel on NES against me or one of my brothers. He'd also play the occasional round of Duck Hunt. That would've been around 1990-1992 or so.
We got a new PC Christmas 1995 and we had Sim City 2000 on that, which my dad liked to play occasionally. He was into games where you build because he was an engineer. Over the next one or two years or so we acquired more of the Sim series of games, some hit or miss. He really liked Sim Tower, while Sim Isle was a bust. He also like Microsoft Flight Simulator, even though he kind of sucked at it.
Christmas 1998 he got me Railroad Tycoon II, but he ended up playing it way way more than me because all I wanted to do was play Halflife.
When my dad retired in 2004 I think he was still playing the odd PC game from time to time, like Sim City 4. I think that was probably the last game he bought.
My Dad's 71 now, and still working (he incorporated himself and became a consultant after his retirement in '04) but I haven't lived with my folks since 2003 so I don't keep close tabs on what he's up to day to day. I have no idea if he's still playing any games anymore. I mentioned anything about it to me in over 10 years.
Most recently in January I got my hands on an NES classic and I hacked it to add more games including Blades of Steel. When my parents last came to visit me a couple of months ago I played a game against my dad, just like we used to 25 years ago. That was cool.
