I'm sort of at a sticking point with the Underworld. On the one hand I want it to be Swords & Sorcery with dinosaur-riders, and on the other hand I'd like it to have a flavor more resembling 500 BCE instead of the 15th century CE. I've also been rereading the old 3.X supplement Ancient Kingdoms: Mesopotamia and now I'm really jonesing for a similar sort of campaign, but I don't have the mental fortittude to use 3.X again in the near future.
So I was wondering if any of my fellow bloggers have ever run or currently run a campaign based on the cultures of Antiquity instead of Late Medieval Europe. I'm particularly interested if they were based on Ancient Greece and the Levant, but I don't mind things about other ancient peoples.
What version of D&D did you use? How did you handle the different classes? How did you handle the different races? Did you change the types of monsters the players fought? Did you use dungeons? Did you have a hexmap? What did you do with the equipment list?
Other comments are fine too.
I'll still be offline mostly for the coming days, but I'll try to check up on replies and things.
