I really like this product.
It is meant to help in those times when you really need an idea for a game, and nothing is coming to you. This should help you get your creative juices flowing. You roll to get a location for your adventure, flesh it out a little, and then figure out what the characters are going to be doing there.
It is pretty straight forward and should be able to help you in a pinch. It is geared towards Science fiction games, with spaceships and moons serving as the items you are presented with but there is no reason you couldn't work it to fit whatever setting you are playing in. That being said, there is a lot of text here that describes stuff and a GM running a space opera style game could surly benefit from it.
the bad part is, sadly, it doesn't do all the work for you. This is meant to give you a solid frame for your adventure that you can then go back and fill in the blanks on. Having used things like this in the past, i know that sometimes that just isn't going to be enough. Still this handles it better than a lot of adventure generators I've seen. Very little artwork, but what art there is, is pretty high quality.
