Work began last night. It's looking like it'll be kind of a bifold product; on one hand, it'll be a genre guide for, you know, Sinbadesque sword-and-sandal adventures, as well as a fully-playable (but not overly-detailed!) game setting.
Actually, my wife is going to detail the world very thoroughly for her own purposes, and we'll put some capsule versions of the setting info into the finished product.
Is "bifold" a word? Mozilla sure doesn't think so.
