"Pantheon Games" is a story for White Wolf's "Scion" game, using mostly the original system and background with a few tweaks and one major change in background: There is no Titan War, the Titans have never escaped from their prison, and the gods therefore spend most of their time with petty bickering, schemes and intrigues among themselves. The characters (pregenerated characters only, I'm afraid) are all children of the various Greco-Roman gods and have been brought along to compete in their own low-weight version of the major pantheon games, while observing the games their parents participate in (and likely getting caught up in some of their intrigues).

Knowledge of the system or background is NOT required, though some basic (really basic) knowledge of Greek/Roman mythology would be helpful.
