There are dedicated teams of gamers from that decade who code compatible programs to run older games like Kings Quest, Space Quest, all older Lucas Arts point-and-click adventure styled games (Monkey Island being my number one), and many other pixelated classics. If you want to try these out, I recommend going with
DOSBox or
ScummVM. Free to download, free to use, though you still need to acquire the actual game files themselves somehow. If you look in the compatibility section, you can see which games they can run well and which ones they have yet to optimize. There are also
various tutorials on YouTube to help you get them working.
