Best free "MS-DOS remake" games

MS-DOS, launched by Microsoft in 1981, was the dominant operating system for IBM PCs and compatibles throughout the 1980s and early 1990s. Short for “Microsoft Disk Operating System,” it offered a text-based interface where users typed commands to manage files, run programs, and control hardware. Its simplicity and wide adoption made it the foundation for countless business applications, utilities, and, of course, a massive library of classic PC games. MS-DOS played a crucial role in popularizing personal computing, paving the way for Windows. Though eventually replaced by graphical systems, its influence endures in modern computing and retro gaming communities.
