I've been really curious about Og for a while... sounds like great fun, with extra awesomesauce!
What's the learning curve like? Is it suitable as a party game with non-RPGers? That is, is it easy to teach/learn on the fly?
No we never did. I'll try to remeber to bring the book and some character sheets. It takes 5 minutes or less to make up characters but unlike other games I think it works better with characters made at the table then pre gens.
Huzzah! Put it in the Games for Gencon forum!
