"It comes in pints? I'm getting one!" - Pippen, The Fellowship of the Ring

There are a lot of very useful supplemental rules in this. The drinking rules alone are worth it for my group—they've very well thought out, and what campaign doesn't have a party who hits the taverns occasionally? I don't know that we'll find a lot of use for the in-game games, but for the right setting or the right diversion, I could definitely see them adding lots of flavor.

Given the huge amount of sheer content in this book, I think it's very likely that most campaigns (save those focused solely on combat) can garner sufficient use to justify the expense.

This isn't a particularly practical supplement (and doesn't pretend to be), but it's a lot of fun! A huge amount of humor for a very low price.
