Did you know that a graphically enhanced port of SkiFree was released on the Game Boy Color as part of a compilation of PC games that included six other games, including Minesweeper and Free Cell.   The Microsoft Entertainment Pack was released in 2001.  Released in 1991 the original SkiFree was developed for Microsoft Windows and was included in the Microsoft Entertainment Pack 3, and later the Best of Microsoft Entertainment Pack.  The game is a high-score based game that puts you in control of a skier tasked with avoiding obstacles, hazards and a rather terrifying abominable snowman along an endless slope. Although simple, its pick up and play nature and addictive qualities make it an enduring classic.  Think about it hard enough and SkiFree could well be the first entry in the endless runner genre.
