I'm currently in the process of preparing to run a campaign using the Hellas: Worlds of Sun and Stone RPG.  I first learned of Hellas during GameStorm 11 last year.  The authors had a booth and I was lucky enough to sit down and play in a game run by Jerry Grayson.

Hellas's game engine is built on the OMNI system from  Morrigan Press.  The basic premise for the system is all roles are made on a single d20 with modifiers then compared to a single results table.  I feel the simplicity is the systems real strong point as it allows you to focus on the characters and the situation instead of crunching numbers.

The campaign world the adventurers travel in it very interesting.  Here is a quote from their website:

In ancient times, the spacefaring Hellenes and their Gods defeated an empire that threatened the entire galaxy. Now, after centuries of darkness, their enemies have returned for a final reckoning, and only a chosen few -- wielding the power of the Gods -- stand between them and certain destruction.

The setting is a blend of ancient Greek ideals and theology mixed with futuristic alien races and technology.  It should be noted that Hellas is not Greece as we know it but is simply inspired by the culture.  Because of the game embraces a few adult concepts, this would not be a game for younger players without being heavily modified.

The player characters are constantly striving to find their places among the gods through glory and actions.  And as with ancient Greek heros, it may take generations before the legacy is fulfilled.  The game plays into this by offering a system where after your character dies, the new character gets written into their history and carries on the legacy left behind by the fallen hero.  This might be a son, daughter, apprentice, or even friend of the family.  This is why it is said that the character a player starts a campaign with will likely not be the one they end it with.

I really look forward to running this game with my group.  For anyone interested in trying it out for the first time, they have a preview of the game available for download at their website.  If you do give it a try, stop by and leave your feedback.  I'd love to hear how it went.
