Today, its rather easy to install games on a game console or PC, but in the image above for Wing Commander 2, installing games way back in the 80s and 90s was a bit hellish. The time you spend today waiting for a game to download was the time it took to install a game way back then with more headaches than you can endure.
It was so hellish, the install set up came with a very dire warning page.
Thank god for modern GUI. Scrolling through the comments in the article above will show the horrors of installing an OS, gruesome!
