This is a large, but not fully comprehensive, list of SkotOS-based and Skotos-Tech-related games.
Some of them have left fragments of code scattered about, while others have not.
- Castle Marrach - CM is, and basically always has been, the largest SkotOS-based game
- Allegory of Empires - a rebuild of Ironclaw Online due to loss of the IP license
- Multiverse; Revelations
The Gables is more of a stage than a game, but it's SkotOS-based and live.
- The Eternal City - still operating!
- Lovecraft Country, which included "Arkham By Night" and a smaller stage called The Oasis; this clearly had a usable beta release and a lot of usable code; it went through multiple dev teams and was, for awhile, the #2 largest SkotOS game.
- Grendel's Revenge - I don't think this one was SkotOS-based, though it was published by Skotos Tech
- Ironclaw Online, - this was based on the Ironclaw anthropomorphic RPG
- The Lazarus Project
- Galactic Emperor: Succession - is this the same game as Hegemony? Or a smaller stage of it?
I believe everything in this section saw a release and later stopped operation.
You can find some history of many things here in this article by Shannon Appelcline.
There were also SkotOS-affiliated games that didn't seem to be based on the SkotOS engine:
There have been various small stages that were never meant to be full-sized games.
Other fragmentary, unfinished or not-well-documented parts include:
- The Skoot On Inn was a small test stage that seems to have existed in several revisions, and seems also to have been called The Tavern and possibly The Hearth
- Headquarters isn't a separate game, but a staff-only area that exists inside several games
- The Mansion, a.k.a. The Gables has existed in several revisions, including the currently-live one
- Regency - an unfinished(?) game involving Regency castles which produced a lot of in-game objects; Regency was a rebuild of Ironclaw Online without the Ironclaw license
- Orphan Crown - this exists in in-game fragments (mentioned here)
- Pendragon Online - this exists in in-game fragments (mentioned here)
- The Devil's Cay - Laurel Stuart wrote a series of articles about building it
- Horizon Station - Sam Witt wrote articles about working on it
- Qigung - Jeff Crook wrote about working on it
- Arcana - Gareth Michael Skarka was attempting to build a horror game and wrote about it
- Glory of the Nile - was to be a SkotOS Theatre; (articles)
- S7 - not a game but a library from the "Skotos Seven" series of game projects
- The Bane - "In The Bane you might be a Sun Worshipper with uncertain loyalties..." - The Bane was one of the earliest SkotOS game attempts and still exists in in-game fragments, often combat-related
- The Welcome Room / The Link Zone - this was an out-of-character chat area, still to be found in some in-game fragments
