World Domination I is a real-time strategy game for the TI-8x series of graphing calculators. It is based on games such as Risk; you battle the calculator AI for control of the world. Each player starts with several units to place around the map of the world, then take turns moving, attacking, and redeploying. If you or the calculator gains control of a continent, you get a number of bonus units. Defeat all enenmy troops to win the game. This game is fully graphical yet with a surprisingly small size, under 10KB. It is of course Doors CS v5.0 certified.
You can download World Domination I at ticalc.org (it's at the bottom of the page). I'll put up a Cemetech file archive page soon.
