Here's a list of fifteen DOS games that I think are still really enjoyable, and worth playing today. It was hard picking only fifteen as there are so many good games. This is by no means a 'top 15', just games that I recommend playing, and in no particular order.

I hope you find something you like the look of. Below are some resources for playing them:
