A couple of things have hit the virtual shelves in the past couple of days that I'd like to point your cursors toward:
Legends of Sorcery Gems, bringing the mystical power of gems to your games, allowing you to embed them in items as a way to enchance them. It also includes the Jeweller low magic class and the Geomancer medium magic class.
Modern System Gangland, updating an older product. If you ever wanted to play a criminal, or just add more interesting felons to your game as baddies, this little book is for you.
