We already have a thread about HR6: Age of Heroes, but I also wanted to create a separate thread for discussing the wide variety of Greek inspired settings and relevant source material for various historical Greek era inspired settings and campaigns.
- HR6: Age of Heroes (TSR, AD&D)
- D&D Supplement IV: Gods, Demigods and Heroes (1976) - Greek pantheon
- AD&D 1st Ed Deities & Demigods - Greek pantheon
- AD&D 1st Ed Legends & Lore - Greek pantheon
- AD&D 2nd ed Legends & Lore - Greek pantheon
- D&D 3rd Ed Deities & Demigods - Greek pantheon
- D&D 5th Ed Players Handbook - Greek pantheon
- Trojan War (Mythic Vistas, Green Ronin)
- Thesseus and the Minotaur, TSR Video Game
D&D / D20 Campaign Settings
- The Milenian Empire
- Hollow World (Traldar & Milenians)
- Monster Slayers: Heroes of Hesiod - It is unclear if this has much of a Greek flavor, but the name Hesiod does suggest this.
- Aesheba: Greek Africa
- GURPS Greece
