Choosing a Game

I have some ideas about my game, but I'm not completely sure. I know that my topic is going to be about greek mythology. It is  going to explain how the Greeks had an explanation for just about everything. They have eleven main gods: Zeus, Poseidon, Hates (those are the main three), Ares, Hermes, Aphrodite, Apollo, Artemis, Athena, Hephaustus, and Pan. But other than those gods, there are many others.
