If you haven't played this superb strategy game you have missed out on a great time. This game is huge with 30 levels which get increasingly larger and more difficult as you go through them. You can also create custom sized maps and select your opponents and their individual difficulty levels....PLUS a 2 player split screen, either co-op or against one another. Truly awesome and on a machine with some fast RAM the maps can be completley monsterous. Superb sound, graphics, gameplay, just perfection.
