I was thinking of games I used to play on my 286 and 486 this afternoon and decided to go looking for some of them. If you want to play these games, you will most likely need to use a program called DOSBox, which is an x86 emulator. It is available for Windows, Mac, and Linux (its open source).
These are just some of the games I played on my 286 and then my 486. There are a few others I don’t have here that I played, I’m sure, but some titles aren’t easily available (even though they are no longer sold).
