Quoting: How This Classic Video Game Helped Spread Linux —
While waiting for his copy of Minix to show up, Torvalds split his time between experimenting with MS-DOS programming tools and playing "Prince of Persia." The former was the beginning of what would become the Linux kernel, and the latter would have a large effect on Linux's future adoption.
While he'd already finished the game by the time Minix finally arrived, he partitioned his hard drive between Minix and DOS so he could keep playing it. The classic game is so great, who could blame him?
