The actual game "Pimpwars" has its start in 1990, and the author was Paul J.
Martino. Paul supported the game for a good many years (until the late
1990's) at which point it has been taken over by other folks, who continue
the development.
Phil is happy enough with his work on Pimpwars that he mentions it on his
website as one of the programs he worked on in his past. (He has since started
his own company, Ahpah Software.)
Current development of Pimpwars is being done by James Coyle of Mystic BBS
fame, who is maintining DOS, Windows and Linux versions of the door. The
version called "Pimpwars 32" is a version of Pimpwars to work with Windows;
it is not a new game.
There is a web version of Pimpwars at PIMPWAR.COM which runs online
multi-player games, sells pimpwar merchandise, and offers IRC chat channels
to discuss the game.
