Conquest is a top-down, real time space warfare game. It was originally written in RATFOR for the VAX/VMS system in 1983 by Jef Poskanzer and Craig Leres.
I spent incredible amounts of time playing this game with my friends in the terminal labs at college, and when I actually had a multi-user system running at home (Unixware) I decided to try and translate/port the code to C in Unix. This was in the early to mid 1990's.
Of course, over the years many things have changed. Today, Conquest is a true client/server game. The client uses freeglut, SDL 1.2 (for sound) and OpenGL.
