Soldiers and Archers have 1 movement point, while the Knights have 2. You buy new units with mana, which you get by controlling territory. The more you control, the more mana you produce. In addition, your units can move farther in one turn when traveling on roads. You can build bridges to get to islands or attack with a larger army.
Trees are impenetrable barriers.
There may be as many as 3 computer opponents on a level, but the good news is that they fight each other . Sometimes the only way to win is to stand back and let the AI's go at it, then finish off the survivor. I had a lot of fun playing this game. Playing the game on easy wasn't too challenging, but fortunately I can backtrack to any level and replay it on any difficulty. However, the final level is extremely difficult, even on easy.
