I'm always up for pimping other OSR products on the ol' PRG blog, soooooo...
Here is a cool new product in which one can mine some great ideas for their LL/old-school game. With Barrataria Games' Companion Expansion, GMs can introduce new spells, magic items, classes (half-ogre!), and rules to slice and dice your characters up to 36th level.
The Companion Expansion is an obvious labor of love and a useful gift to the OSR. You can check out the no-art version here for FREE! Barrataria plans to release a POD version soon, filled with glorious art and old-school happiness.
Give it a test-drive to see if a little (or a lot) of the CE can fit into your current game.
