It's a somewhat useful list of planets and their makeups. Unfortunately, unless you are very good at chemistry / biology, you may not know whether the air composition is poisonous or not. A little blurb about each planet and pictures would have made this a 5 star product.

This is a fine collection of planets with all the astronomical and astrophysical data that a typical survey would return, provided for you in a nice orderly manner - just the thing when your characters abandon the starport and decide to go on a wander around the galactic neighbourhood without warning!

Created using the random generation tables already published by Ennead Games, they read well. There are occasional anomalies but finding out an explanation for them can often result in something far more interesting than an instrument survey.

Top marks to the publisher who, after I posted a review praising the contents but commenting adversely on the layout and some stray links (to their own planet-generation software routine!) that had been left in but didn't work, laid out the complete product in a far clearer and user-friendly style!
