I found this game for one dollar at a thrift shop, and looking at the screen shots on the CD case, figured it must be junk. Wrong. The theme is a bit hokey, and the graphics are a bit crude, but the gameplay is deceptively deep. You really must THINK, hard and long, on each of your moves. The game has all the depth of chess if you give it a chance. Several settings speed up or slow down movement or combat, if watching such things bores you. You can even click a button and watch a replay of your opponent's last move, to get a better idea of what the computer is plotting against you.
If you are used to Real Time Strategy games such as "Civilization" or "Empire Earth", you'll find this familiar, but refreshingly different. You'll have plenty of time to plan your moves, and you'll need it after the handful of easy introductory missions. To get some very useful pointers, go to google and find the Walkthrough that's out there, it's awesome.
