Massive work with lots of nice details. It is really designed with a sandbox look at the game universe and it gives a lot of help to maintain the game world feeling right)
System is accessible and coherent. Stats on 3-18 and the usual bonused at both end of that scale.
Character creation is limited to basic classes with a very "old D&D" feeling in a science-fiction setting.
Book gives plenty of ways to add things to a campaign (factions etc), like Traveller and its offsprings but in an easier way.
If i have a complain it would be that' i'd like to have more objects, artefacts and psionics
However, I really llike it.
Best free SF DL I got ever.
Will play it soon.
