I would throw the equipment list book …and a 10-Foot Pole from Iron Crown Enterprises. Though primerally a Rolemaster book, it is very system agnostic. It is currently not in print as far as I can see, however still worth a read if a copy can be found.
Yep been using the same world for about 20 years now. Have tended to set the games at different historical points, so a few 100 to 1000 years apart - mainly as the groups of players don't know each other and there is no link, also I enjoy seeing how different things happen. Also used it across...
That would likely be the fifth Edition supplement Realms of Power: The Divine which has a chapter on Mythic Judaism. Though I've not get any of the fifth edition books beyond the core, so haven't read it.
