Guardians Of Order(link) makers of such great things as "Big Eyes, Small Mouth" and publishers of "Tekumel".
Go look up Tekumel. I dare you. I have my copy, which I bought at Portland's greatest bookstore (well in my opinion), Powell's. Oh, and any city that has a technical bookstore with tons of books and another store with tons of rpg's and others is just awesome. Although, seriously Powell's, why is some of the anime in the children's section?
