Because of the Greek Mythology becoming more popular thanks to Percy Jackson and the Olympians and The Lost Hero, I think Lego should come out with Greek Mythology sets.
There could be one small set for each God/Goddess and eventually there could be Titans added. Each set would have it's own god, and there could be bigger sets, The Labrynth, Pereus and Medusa, Herclues and Chiron, The Trojan Horse, and so on.
Zeus's Throne (With 3 lightning bolts)
Hades' Throne (With Persephone)
Poseidon's Throne (With Trident and 1 Cyclops)
Artemis Hunting a Golden Deer
Aphrodite's Mirror and Cabinet
Dionysus's Grape Vines
~ DEMIGOD BATTLES/HISTORICAL MOMENTS ~
Perseus and Medusa's Lair
Hercules Fighting Cancer or Taurus
Theseus & The Minotaur
Achilles On His Chariot
Orpheus With His Lyre
The Oracle of Delphi's Place
Demigod Battles, Important Wars, and additional God/Goddess adventures will be added later.
