ZFootBall – developed and released in 2004, this was the first complete soccer-themed total conversion for ZDoom.
The first version of the modification was developed in winter 2003 and was made almost entirely on Dehacked. It didn't have a digital scoreboard yet, and the ACS scripting system was very primitive. Within half a year, we managed to make significant progress on the project and release the second version.
Almost all the code was ported to ACS, new levels were added, and stadiums were revitalized. Probably, by the standards of those years, it was if not the first, then certainly one of the first truly international ZDoom-projects, as players from Russia, as well as from the USA and Canada actively helped in the development. It was a golden time. :)
