I think you may have the Revised Edition (updated 1st edition) boxed set as there is no 2nd edition boxed set.LastBest said:
To have pretty much everything you need for 2nd ed. you need the 2nd ed. rule book and the 2nd ed. fleet lists books. P&P gives you some extras, tweaks some stats, has the Gaim fleet, etc. but isn't essential to play Crusade and most of the main stuff you'll want to do.
