90s PC Games: A Guide by Genre and Operating System
"90s PC gaming" wasn't one thing. Depending on what was in the box under your desk, it meant typing commands into a black DOS prompt, clicking through Windows with a mouse, or booting a beige Macintosh into a completely separate library of games. This guide is the map: what actually separated DOS, Windows, and Mac gaming, which genres defined the decade on each, and which of our deeper platform and franchise guides to read next.
Play the original Doom & Doom II on a modern PC
Doom 3: BFG Edition bundles the original 1993 Doom and Doom II (as a "Classic Doom" mode) alongside Doom 3, a straightforward, officially licensed way to run the exact DOS-era games discussed above on modern Windows.

At a glance:
- DOS: the decade's default for most of the 90s; direct hardware access, manual configuration.
- Windows: shaky before DirectX (Sept. 1995); standard from 1996's DOOM95 onward.
- Mac: its own smaller, mostly separate library of exclusives and shared CD-ROM titles.
MS-DOS: the decade's default
For most of the 1990s, DOS was where PC gaming actually happened. DOS gave a game direct access to the sound card, graphics hardware, and memory, which is exactly what CPU- and memory-starved 90s games needed, but that same directness meant every game had to be configured for your specific setup, and getting sound working in a new game was a genuine skill. Landmark DOS releases spanned the whole decade, from Wolfenstein 3D (1992) and Doom (1993) to Warcraft: Orcs & Humans (1994) and Command & Conquer (1995).
Windows: a rocky start, then DirectX
Early Windows (3.1 and the first release of Windows 95) wasn't built for games: its multitasking and hardware abstraction made it feel slow and unpredictable compared to DOS. That changed with DirectX, Microsoft's Windows Games SDK, first released in September 1995. DOOM95, released in August 1996, was the first game built on DirectX and ran more smoothly than the original DOS version while adding higher resolution and simpler multiplayer setup. It's the moment usually cited as when Windows became a credible gaming platform in its own right, and by the back half of the decade new PC games increasingly targeted Windows instead of DOS.
Macintosh: a smaller, separate library
Classic Mac OS ran very little of the DOS/Windows PC library. Instead it had its own, smaller catalog: some shared multi-platform CD-ROM titles (like Myst), and a set of genuine Mac exclusives. Bungie's Marathon (1994), a first-person shooter answering DOS games like Wolfenstein 3D and Doom, is the best-known example, followed by Marathon 2: Durandal (1995) and Marathon Infinity (1996).
Standout games by genre
A short, cross-platform sampler. Our platform-specific guides below go much deeper on each:
- First-person shooters: Wolfenstein 3D (1992) and Doom (1993) on DOS defined the genre; Marathon (1994) did the same for the Mac.
- Adventure & puzzle: Myst (September 1993) and The 7th Guest (1992) showed what CD-ROM storage could do with full-motion video and high-resolution art that floppy disks couldn't hold.
- Real-time strategy: Warcraft: Orcs & Humans (1994) and Command & Conquer (1995) on DOS helped define the RTS genre as we still know it.
Hardware and control differences
- DOS: you managed your own sound card drivers (Sound Blaster and its many imitators were the de facto standard), juggled conventional and extended memory, and configured each game individually.
- Windows: once DirectX matured, sound, graphics, and input handling were standardized, so games worked more consistently across different PCs without per-game driver fiddling.
- Mac: generally required less manual configuration but ran fewer titles overall; the tradeoff was breadth of library, not ease of use.

Frequently asked questions
What's the real difference between DOS games and Windows 95 games?
DOS games talked to sound and graphics hardware directly, which made them fast but meant every game had to be configured for your specific sound card, memory setup, and drivers. Windows games from 1995 onward used Microsoft's DirectX, introduced in September 1995, which gave games a standard way to reach the hardware. DOOM95, released in August 1996, was the first game built on DirectX and is usually pointed to as the moment Windows gaming became a real alternative to DOS.
Could 90s Mac computers run the same games as PCs?
Rarely, and not by default. Most DOS and Windows games were never ported to classic Mac OS. Some multi-platform CD-ROM titles (Myst is the best-known example) shipped in hybrid or separate Mac versions, but a lot of the era's biggest PC franchises simply weren't available on Mac. The Mac had its own smaller library of exclusives instead, such as Bungie's Marathon series.
What was the first CD-ROM game?
There isn't one single "first" CD-ROM game, but The 7th Guest (1992) is widely credited as the title that proved the format, using its storage space for full-motion video and high-resolution art that a floppy disk couldn't hold. Myst followed in September 1993 and became the format's breakout commercial hit.
Do I need original 90s hardware to play these games today?
No. Many 90s PC games run on modern Windows through compatibility layers or official re-releases on stores like Steam and GOG.com, and DOS games specifically can run through DOSBox. Our separate access guide covers platform-by-platform options in more detail.
