You play a party of 3 people, where 2 are controlled by the AI. One of the greatest things in this game is the combat control. You move by clicking on the point where you want the character to go, but when a fight is engaged, you have to hold the CTRL button and use mouse gestures to defeat your enemies. Additionally there are special-moves, spells and food to regain health.
It was the first game i've played that used this kind of control, and i was amazed by it. Think i have to replay it sometime again.
