The last of the original line of Star Wars space combat games, Star Wars: X-Wing Alliance represents the culmination of the series with both single and multiplayer modes, a more modern game engine, and fully voiced in-game dialouge.

NOTE: in the DREAMM source port (since DREAMM translates/emulates the original game) this game requires a joystick and apparently they're not kidding about that as it kicks you out if it doesn't detect one.

From a time when it seemed LucasArts could do no wrong, Star Wars: TIE Fighter is a space simulation game that flips the script on the original Star Wars trilogy, putting you in the role of a TIE Fighter pilot for the Galactic Empire. You must complete a series of missions that involve defending the Empire's interests, hunting down Rebel Alliance targets, and engaging in tense dogfights with enemy ships. The game features a deep and engaging storyline, a variety of ship upgrades and weapons, and detailed graphics and sound effects that bring the Star Wars universe to life. With its challenging gameplay, complex strategy, and innovative features, Star Wars: TIE Fighter is another true classic of the space simulation genre.

Famed Amiga developer Bullfrog released this second entry in the "Theme" series (following Theme Park) which allowed players to design and run a hospital. The name Theme Hospital may not make a ton of sense but the game was ridiculously popular. The CorsixTH project is one of the more thorough and well organized source port projects active today, and Mac Source Ports is handling the Mac build.

I may have overused the term Cult Classic on this site, but this game goes one step further: it's one of gaming's Holy Grails.

No One Lives Forever 2: A Spy in H.A.R.M.'s Way is the second entry in the NOLF series. You play as Cate Archer, a spy for U.N.I.T.Y., a British counter-terrorism group fighting the H.A.R.M. organization. Basically it's a parody/homage to the James Bond movies of the 1960's with a stylish, groovy protagonist. The game was critically well recieved and is beloved within gaming fandom.

So why is it a White Whale? Because it has been commercially unavilable for many years now. It's a bizarre situaiton where the companies involved with making the games have been bought and sold and absorbed enough times that no one knows who owns the rights. The parties involve are willing to spend the effort to quash efforts from GOG and Night Dive to reissue the game but not enough to actually hash out the rights.

So consequently it was absolutely not on my Bingo card for this year that someone would figure out how to run the game on Apple Silicon. So if you fall in the Venn Diagram of people who want to play this game and are willing to figure out how to get the data on your Mac, prepare yourself for one of the best games money can't buy, though not for lack of trying.

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.

Long before the franchise became known for the MMO, the Warcraft series started out as a series of real-time strategy games. The original game was a hit, following the conventions of the then relatively new genre, but Warcraft II: Tides of Darkness upped the ante in that golden age where a sequel could follow a year later and be radically improved.

In Warcraft II you choose a side, Orcs or Humans, and collect resources to build an army to destroy the other side. The game introduced several mechanics and interface decisions that would become standard conventions.

Note that the source ports featured here need the original versions of the game, not the later Remastered versions.

Developer: PopCap Games
Release Date: May 5, 2009

Plants vs. Zombies is an example of casual game perfection, from developer PopCap Games at their peak, pre-acquisition. Effectively a tower defense game without being a tower defense game, it has a difficulty curve so incredibly well done that at some point you're pulling off elaborate strategies without ever feeling like you're not ready for it. With an addicting amount of depth, additional mini-games once you finish the campaign, and no microtransactions or mismatched mechanics, it's a game that absolutely holds up.

It's also a game where I had no idea there was a modding community, let alone a nearly perfect reverse engineered source port nearly five years in the making. I honestly thought for a minute it was some sort of trick but no, PvZ Portable is a true reverse engineered port.

NOTE: While PvZ-Portable definitely works with Plants vs. Zombies: Game of the Year Edition, I'm not clear if it works with the regular (non-GOTY) edition. As of this writing the GOTY edition is the only version on Steam. As far as I can tell it does not work with the recent Plants vs. Zombies: Replanted edition.

Although never as big as Mario or Sonic, Jazz Jackrabbit did well enough with a hungry PC gaming crowd to merit a second game in the series. It's your standard shareware sequel story: more levels, more twists, better technology. If you liked the original you'll like this one.

It also has a very confusing release strategy. The original game was shareware, when you bought it you got the full Jazz Jackrabbit 2 game. Later, it was re-released with an additional episode under the title Jazz Jackrabbit 2: The Secret Files. Then came a release called Jazz Jackrabbit 2: The Christmas Chronicles, which adds Christmas-themed levels. So when you get the game on GOG you might spot two entries, neither of which look like they're the base game, but both should work in Jazz² Resurrection.

The story goes that Activision commissioned an expansion pack for Return to Castle Wolfenstein, which like the base game would offer both a single and multiplayer campaign, each assigned to different developers. For whatever reason, the single player campaign did not meet expectations while the multiplayer component was coming along nicely so the decision was made to cancel the expansion pack but release the multiplayer portion standalone for free as Wolfenstein: Enemy Territory.

Although we have numerous options today, in 2003 this was an almost unheard of phenomenon: a free game with no strings attached and whose tech for mods and map making were already in use by the community. In 2010, the source code for the full game was released and the ET: Legacy project has been actively maintaining for years now, with an enthusiastic player base continuing to populate servers two decades later.

NOTE: due to the nature of compiled mods, not all servers may be playable for non-Windows players. Look for servers running the "Legacy" mod for the best chance of connection success.

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.
