The best-selling (old) PC games

It's not easy to compile a list of the best selling PC games of all time. Why? Because the video game market changed dramatically in the past decades and if a game that sold 100000 copies 30 years ago was considered a best seller, it's not the same thing for a game that sold that many copies just a few years ago. That's why this is an unordered list of the best selling games and not a chart.
