I'm in my mid-50s. I play Warzone 2100 and BOS wars on my computer. I've has Steam for several years, and have a game there....I think it's "World of Goo." I like to stick to games that serve as stress relievers, and take no more than about an hour. Between owning a business, 2 teens, 3 schools, 4 sports, a wife, a house that would love to fall apart if I'd only let it, a lawn to mow, and 2 antique cars I love to keep driving, I don't have much more time to let myself be sucked in to some of the really cool stuff I see.
I recently bought a replacement PS2 though...the old one broke, and I'm still in love with GTA Vice City. I usually just steal a cop car and do vigilante mode until I'm killed though.
Oh, you can set up a dual boot system, so you don't have to completely jump ship. They also have setups that run entirely on a thumb drive now.
I did dual boot for a little bit when I want into business 14 years ago. While I liked Linux, I wasn't sure I could run a business without Windows, but soon discovered that everything would be just fine without Windows, and got rid of it.
