Most are hosted on https://sourceforge.net .
When using the search input box there, it brings around 20 hits.
Unfortunately around half of the Crossfire related projects stopped submitting files after a short time,
indicating, that the Crossfire source code base is too large to work on as a single programmer.
Home page : https://www.atrinik.org , pretty huge in red colours, similar to crossfire.real-time.com .
GitHub : https://github.com/atrinik/atrinik , says “RPG with 2.5D isometric graphics, with concepts based on Crossfire and Angelion.” .
Seems to deploy the same standard port as Crossfire ( 13327 ) ,
but connection failed using a stock GTK2 1.70.0 Crossfire client
to game.atrinik.org listed on https://www.atrinik.org/page/servers_list .
CrossCiv is still up, people can connect as of February 2018.
CrossCiv code is hosted on sourceforge : https://sourceforge.net/p/galacticmilieu
It's wiki at sourceforge is explaining much.
The player needs to be a normal character that does not use magic or prayers to access the galactic milieu.
Otherwise, the character is send to a usual crossfire-style fantasy world, with an uncommon starting island map.
The client to connect to crossciv.no-ip.org needs to be v1.60.0 or newer, to play it fully functional.
The Crossfire Extended seems to be split into two projects on Sourceforge :
It appears, that former main map developers like “mikeeusa” had to abandon the Crossfire project, and uploaded their way to SourceForge.
The ChangeLog entries suggest, that they were forked already short time after the release of version 1.9.0 of crossfire.
It's main page says :
Contains old features that were loved (but were taken out of regular crossfire) weather generation etc.
A crossfire from another age.
If you like the pre 2008 CF, here it is with lots and lots and lots more maps!
More archtypes and items.
Including full new building sets: germanic, candy-kingdomish/russian, japanese, middle east.
The source code tarball includes pre-build executables for 64bit kernels.
It says not much there :
Rehash of crossfire for newer OS
Whatever that means …
Home page: https://www.daimonin.org/ , pretty huge in dark red-brown colors.
Wikipedia: Has a few languages available, but *not* in the English language ( Czech, German, Italian, Lithuanian, Portuguese, Swedish ) .
Daimonin source code is hosted on SourceForge :
Cvs access did not work for me, since the source is set read-only.
Using rsync, it needs then the rcs package installed,
to extract it's `,v' archive files using `rcs co' , which is short for checkout.
Status : no current downloads, cvs archive access through rsync, difficulties with bugs in the old client crashing the server
Noteworthy the 9 Stupidities, however they have implemented these.
