The BBS door game
version of the Risk board game
is truely one of the classics. The concept behind it is borrowed from Risk, but GW
adapted it to an early digital
medium. It was immensely popular on BBSes
in the 1990's, and still has a cult following today.
The world map is an ANSI image
of the planet, and armies are denoted by color. It's turn based, with turns resetting every night when the data files cycle
Very popular game on WWIV
-based boards for some reason...
