Return to Castle WolfensteinDeveloper: Grey Matter Interactive
Release Date: November 19, 2001
Source Code Release Date: August 12, 2010
Return to Castle Wolfenstein is a fantastic single player game with lots of little touches you might have missed the first time around and that you don't see much anymore. Still abolutely worth firing up just to blast some Nazis. This source port also includes the multiplayer as a separate app, which still works on the servers running to this day.

Warzone 2100Developer: Pumpkin Studios
Release Date: April 10, 1999
Source Code Release Date: December 6, 2004
Warzone 2100 is a post-apocalyptic real-time strategy game from 1999 whose source was released in 2004 and whose content was released as freeware in 2008.
Although my aim is to host signed and notarized game bundles on Mac Source Ports, the Warzone 2100 Project has done incredible work on this port and has logistical reasons for not being notarized yet. While they work through that process, I decided it was worth making an exception to the site's policy so that Apple Silicon gamers looking for a full, free and polished RTS would be able to find it.
Because the app bundle is not notarized, on first run you may run into issues. The shortest answer is to right-click on the app bundle (wz2100.app) and select Open. The long answer is here.

Jazz Jackrabbit 2Developer: Epic MegaGames
Release Date: May 7, 1998
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.

AmbermoonDeveloper: Thalion Software
Release Date: April 11, 1993
Source Code Release Date: May 7, 2023
The Commodore Amiga was one of those computers where it jumped ahead of the competition by several miles, but then stayed there for a long time and got surpassed by the competition. I think this is why there's such a distinctive look to the games the platform and why it was so accessible to smaller game designers, the types we'd call "indie" today.
Ambermoon is an RPG for the Amiga that really looks like an Amiga game. It was the second part of an unfinished trilogy. Although the original game's source has been released, the source port we're pointing to is Ambermoon.net which like it sounds is a recreation of the original game in C#/.NET (the original game was Amiga-specific Assembly language and isn't a great candidate for portability).
In addition to being able to download it below from the developer's GitHub page, the game is also available on itch.io as a "Name your own price" download in case you want to support or tip the developer.

MarathonDeveloper: Bungie
Release Date: December 21, 1994
Source Code Release Date: January 2000
The year is 1994. The world can't get enough of DOOM. Everyone that is except for you because you own an Apple Macintosh and DOOM is a PC game. You comfort yourself with your superior port of Wolfenstein 3-D but it's just not the same.
Bungie Software Products Corporation to the rescue! Marathon was released as the Mac's answer to DOOM, and a game which was its opposite, as it was not on the PC. Bungie would go on to make a trilogy of games in the Marathon universe before starting work on the Mac-exclusive Halo
Of course what really happened is Microsoft bought Bungie and Halo became an Xbox exclusive. Halo and Marathon may not share a universe, but Bungie put Marathon references in all of their Halo titles, including embedding the Marathon logo in the original Halo box art.
Bungie released all three Marathon titles as freeware in 2005 so the downloads from the Aleph One project include the entire game. No need to dig out your old discs here.

ExtractorDeveloper: Tom Kidd / Mac Source Ports
Release Date: February 23, 2022
Extractor is an app from Mac Source Ports that extracts files from GOG Windows-based installers. Think of it as a GUI version of innoextract.
Right now, Extractor does exactly two things: lists the files in an installer, and extracts the files from an installer. We hope to expand it in the future but for now it's a simple application.
