Mac Source Ports

Developer: Epic Games
Release Date: May 22, 1998

Also known as that game that convinced you to buy a Voodoo card, Unreal was released in 1998 after a lengthy development cycle. Although the name Unreal is primarily known today as a game engine licensing powerhouse, the original entry in the series is more than a tech demo, it's a fasinating glimpse in to what it was like to try and make a polygonal FPS game before most of the rules were well known. It's also a perfect example of a game where what you remember is much different than what you play today.

The OldUnreal team, responsible for bringing us the Mac port of Unreal Tournament have received permission from Epic to also release a build of the original Unreal for the Mac. Although the original game was available for classic Mac OS, this is the first Mac port of it in... nevermind how long it's been.

Note that we are labeling this an Early Access release since the OldUnreal team is labeling this build a pre-release. The original renderer has been replaced with a new Metal-based renderer and some glitches are to be expected, but the game is definitely playable.

Developer: Quetoo Team
Release Date: May 22, 2026

So this is interesting, I just stumbled on this randomly a few weeks back right after it was released, although it was apparently in the works for twenty years.

Quetoo is an open source project that's a combination of id Tech engines and technologies, incorporating every graphics technique the source port communities are known for, and recreating some of the classic maps of the Quake series without actually using any of its data.

The result is a purely community focused freeware arena shooter that can even be edited with modern tools like Trenchboom.
Definitely one to keep an eye on.

In the annals of classic and retro gaming, Infocom's rise and fall is one of the most documented and well followed, with books and documentaries on the subject. Their downfall was due to a number of factors, including an ill advised attempt to break into the database market, but also because by design the nature of their text-based Interactive Fiction games became dated once computers got better at graphics.

Zork Zero was their attempt to bridge the gap. It's also one of their last games. It's also a prequel to the other games, and until recently Splatterlight didn't support it. Custom support was rolled into the latest version so now it's easy to experience the game so fire it up and imagine an alternate universe where it was successful Infocom went on for decades.

True story: I'm old enough to have experienced the concept of buying Commodore 64 software in toy stores as a kid. I'll never forget, it had to have been at the tail end of the C64's lifecycle and I'm going through this bargain bin and finding nothing interesting, and then I stumbled across Zork I, in what had to be one of the slim case budget re-releases. I had no idea what it was other than I had read the name in Family Computing magazine.

I go home, fire it up, it takes forver to load... and then only when I'm sitting at a text prompt does it hit me that this is a game without graphics. No wonder there were no screenshots. I'm pretty disappointed. I'm also bored and have nothing better to do so I start playing it.

What follows is legit one of the best gaming experiences of my life. There's a reason this game is famous - provided you're willing to give it a shot the premise, writing, puzzles and exploration concepts will lure you in, and the anachronistic hodgepodge of elements makes for an eclectic universe. You descend downwards into the ruins of the Great Underground Empire, now an abandoned world.

The backstory has been told at length elsewhere but the short version is that some computer scientists at MIT made a text adventure game called Dungeon to run on their mainframe and got the idea to make a company to sell versions of it for home computers. It proved to be too big to fit on the computers of the era so they split it up into a trilogy of games called Zork. The company was named Infocom and they are beyond legendary in retro gaming archaeology circles.

The technology the games ran with has been reverse engineered so well that an entire community has spawned programming languages and toolkits to make new games with it and there's hundreds of text advantures as a result, including an annual contest that's been running for decades now.

So unlike most games on this site there are literally dozens of options to play these games, and the current best in breed for the Mac is called Splatterlight.

So as mentioned, the original gamed Dungeon was split into three games, so the second game picks up pretty much where the first game left off, diving deeper into the intricate underground realm of the Great Underground Empire as you navigate through mystifying chambers and encounter enigmatic characters. Unravel the secrets of the all-powerful Wizard of Frobozz, solving perplexing puzzles and overcoming perilous obstacles along the way.

The last in the original trilogy and the last part of the original Dungeon game, this game features the deepest portion of the Great Underground Empire where you must face the wrath of the vengeful Dungeon Master as you journey through a treacherous underworld filled with ancient secrets and unimaginable dangers. Traverse through stunning landscapes, unravel mind-bending puzzles, and confront cunning adversaries in your quest for redemption. Might as well keep going if you've gone this far :)

Beyond Zork is an interesting entry for a few reasons. It's the first Zork game not derived from the original larger Dungeon game, and it was made after Infocom made an ill fated venture into business software. And it tries several new things as the technology evolved - instead of just being a text adventure it incorporates RPG statistics and combat elements, along with a crude on-screen map. It both is and is not more Zork, but it's worth checking out at least.

Another game from Chris Sawyer, Locomotion served as his spiritual successor to Transport Tycoon and like that game and Rollercoaster Tycoon the game has his signature isometric pixel art style and a hardcore group of followers willing to reimplement and reiterate on it in the form of open source projects. The OpenLoco team recently hammered out the issues necessary for their project to work on 64-bit operating systems so I've made a build of it available here.
