The idea is to use hidden information about optimum paths and opposing army disposition to create a game where a somewhat random strategy is required.
You get points/money for picking up valuable items, killing enemy units, reaching predefined goals, etc.
During Action, you may be able to interact with units - using their targeting abilities to somewhat modify their behavior.
At the beginning of every round units can reset their position or continue from where the left off. If they continue, it becomes more like Baldur's gate, a strategic non-realtime combat simulation.
