Windows XP solitaire was peak gaming.

Some-what related funny story: at my old job we removed the built-in games from Windows as part of our Windows 7 rollout. Most people didn’t even notice, but the director of public safety was so upset that he demanded (not just asked) we put them back on his computer. When we refused he went to his DOCTOR and got a note stating that he needed Solitaire on his work PC as it helped him manage his anxiety. I was flabbergasted.
