Though I am a huge fan of the Star Wars Minis game, I am not a big fan of the scenarios in this book (some are pretty good, but most are not). However, there are several things I liked about this item that I thought worth sharing. The best thing about this book are the two maps at the end:
Map 1: Coruscant -- A very good to great map that is legal for 100 and 150 point tournament play. Works best with shooters, but melee characters also stand a good chance on this map.
Map 2: Geonosis Arena-- A very good map that is unfortunately no longer legal for official tournament play (but still a fun choice when playing a casual game with friends). Shooters have a moderate advantage on this map.
A couple of other nice things about this item is that there are several terrain tiles of various sizes, as well as Appendix with special rules for how to use some of them at the end of the book.
In sum, I would not necessarily buy this book for the missions (which make up 75% of this book), but this item is definitely/still worth getting for the maps, terrain tiles, and the special rules that make up the rest of the book.
