An excellent multi-player game, but has two major flaws. First, it takes forever to play. Second, the random calamities can completely take you out of contention if you're unlucky enough to get several "complementary" ones in a row.
My rating for this item reflects not my interest/willingness to play Ogre as much as it reflects the amount of cool information that's in this sourcebook. If you're a big Ogre fan and get to play it a lot, you'd be remiss if you didn't try to find a copy.
