It's not really a true RTS. It's an RPG, but there's a real-time strategy movement system involved -- similar to Ogre Battle, Ogre Battle 64, and the Growlanser games. That's my understanding of things.
It's still at its core an RPG, though, as the characters are leveling up through their actions.
Eh, it has to be an inverted pentagram for it to be directly tied to Satanism....
Satanists use an inverted Pythagorean pentagram (one point down), often inscribed in a double circle, with the head of Baphomet inside the pentagram. They use it much the same way as the Pythagoreans - after all, Tartaros does mean Hell in Christian terminology (the word is used as such in the Bible, referring to the place where the fallen angels are fettered). The pythagorean Greek letters are most often replaced by the Hebrew letters לויתן forming the name Leviathan. Less esoteric Satanists (LaVeyan types; the ones that exist in abundance) use it as a sign of rebellion or religious identification, the three downward points symbolising rejection of the holy Trinity.
