Ancient Wars: Sparta is a little late to take advantage of 300. The hit movie should have primed a large audience for a real time strategy game set in the historic struggle between the Greeks and Persians. The opening scenario in the Spartan campaign sets the stage for an extended flashback wherein King Leonidas explains why he has decided to undertake a hopeless mission in defense of all Greece. But it doesn't work.
Gamers will be more inclined to ask why the developer decided to engage such a hopelessly antiquated design that takes classic RTS design and adds unnecessary levels of micromanagement. Customizing units sounds like a better idea than it turns out to be and the medic units require too much clicking and hovering. Better to churn out skirmisher cannon fodder.
