Seven Stats are rolled on 2D3+8. Then you have a class that gives you a skill and a homeworld that gives you a +1 to a stat.

Tests are made on 1 or 2D20 vs stat with the classical advantage/disadvantage process of using 2 dice and keeping best or worst. So the grid of difficulty is a mere 3 pints setting. Why using D20 for such a simple procedure? A single couple of D6 would have been plenty.

Also I think the document is incredibly bland, no editing, no pics, no setting info, no whatever. Frankly: no more than 3 stars.
