I built one of my best friends a retro gaming station out of a raspberry pi 2. Its called the Nicolas Cage SuperStation. We've been playing old school streets of rage with our ps4 controllers.
You can download the operating system, LakkaOS, from here: https://www.lakka.tv/
We also play Death Stranding and were about to get into the new Marathon too
In the 90s, my father had an IBM running DOS so he could get work done at home. He also had a huge floppy of Friendlyware, which was a suite of family friendly games. Some of these were clones, but they all definitely had their charm. I played the hell out of those games. One of my best childhood memories.
Me and my sister would also love to type gibberish at the DOS prompt and try to pronounce what crazy mess we typed. That was a game in and of itself.
