geoWar v1.0 by Lysle E Shields III (August 20th, 1988) is a turn based strategy game of world domination for the Commodore 64 and GEOS operating system.  The game is based on the board game RISK! The standard rules follow RISK! to the T, but you can also change them.  The game is very solid and fun to play with up to 6 players of which a computer can play any of them, or you can just leave some of the players as neutral territory.
