This is pretty meaty for a free preview of a new game. The game itself is a setting agnostic system designed to help you build your favorite sci-fi setting. It's towards the crunchier end of the spectrum.

This does give what you need to decide to get the game or not. And gives more details than most such previews in that it at least shows how the game is played if not how to do it. (how to do it is in another free offering.) So it does the job in superior fashion.

Meh. It looks professionally done but I don't like the game system. I find it too qualitative and arbitrary, so you can't be sure that gameplay will be consistent unless you really know your GM.
