I got it and i quite like it.
Things that are covered to give you a rough guide if you decide to buy it:
*List of races that have the potential to be a Ranger as well as the political relations between the ISA and them,
*Extended history of the Rangers from before the Legend of the Rangers movie to post Drakh War and into the distant future that we saw in that one Babylon 5 episode.
*Detail on the Hand, their history, motives and the type of enemy you are facing.
*A few new classes that Ranger players can take on.
*I think maybe 4 or 5 ships are shown in the book along with specialist Ranger equipment that can be used.
*A scenario at the end that details how a game can be made with a Hand agent being the enemy.
Hope that helps.
