Disclaimer: Currently I am employed by Microsoft, but my views and thoughts are still my own. The reason I joined Microsoft was, the work Microsoft have been doing for last couple of years in Open Source Space. Today I am a advocate for Open Source representing Microsoft.
SkiFree was part of Microsoft Entertainment Pack 3 for Windows and DOS released back in October 1991. Over the years, there have been several ports of SkiFree to different platforms. But back in February 2020, Microsoft decided to include a new version of the game as a Surf game as part of new Microsoft Edge.
