"In 1972 I created the concept of Mazes & Minotaurs, the world's first roleplaying game. Inspired by my fanatical interest in ancient Greek and Macedonian wargaming, coupled with a love of Greek myth and the 1963 movie, Jason and the Argonauts, it took the gaming world by storm." -- Paul Elliott.

Olympus Overdrive is a webcomic in which the gods of Greek mythology compete to replace Zeus as the ruler of Olympus. Each deity is rebooted into the modern world and bound to a mortal companion, and together they must try to defeat the other teams. The winner immortal gets Zeus's Thunderbolt, while the winner mortal gets anything they desire. [Via]
Theoi Greek Mythology is an internet encyclopedia with over 1500 pages on various characters from classical myth, covering everything from famous gods and goddesses to obscure nymphs, titans and monsters. If the confusing familial relations of the Greek gods vex you, there are 10 different family trees to help you make sense of it all. There's also an extensive library of ancient works concerning classical mythology and a bibliography should you long for more to read. Last but not least, Theoi has a gallery of over 1200 artworks from antiquity, which I have been happily browsing for a good while.
Greek Mythology told in a much different manner than when I was in school. Check out Achilles' page, where you can play the Iliad game. Test your knowledge of the epic story. The illustrated Cupid and Psyche story is...interesting.
