cconq is a version of Xconq that requires only an ASCII terminal and a curses library for cursor movement and screen management. As a result, it will run almost anywhere.
However, in exchange for this higher degree of portability, you lose a lot in display power, and games may become much more difficult to play. For instance, roads and rivers cannot be represented directly, and you will have to rely on the textual displays to see which directions have them.
(Incidentally, this curses interface is the oldest one in Xconq, predating even the X10 interface that was part of version 1's release in 1987.)
