Does anyone know if there are any plans of fanmade supplements to make Lord of Olympus a traditional RPG with dice? I'd really rather play it with dice as a randomizer, rather than diceless.

I'm thinking about creating a dice version when my time frees up from other projects. Probably using the Supergame 3E mechanics. You could probably combine the two yourself.

I have that game but not sure how to translate LoO into it.

Something quick and simple off the top of my head. Any such actual game version would work differently apart from the rating scale.

Mortal: 1-4
Heroic: 5-9
Olympian: 10-15
Numbered: 16+

Ego = Insight
Average of Prowess and Might = Fitness
Fortitude = Toughness

Treat powers as powers, given a rating equal to the corresponding ability.
