SFB is a great game. 2-stars is for the lack of a table of contents in the PDF. Yes, there's the printed TOC at the beginning of the book. This is 2023. PDF files should have the clickable TOC embedded, to make navigation easier.

Probably the most complicated game I've ever played. You'll need to look up rules... a lot! But, I learned this game with my brother as a 12 year old. With enough love for space combat and Star Trek, you might have the motivation to learn it. (We made a lot of mistakes along the way!) It is a very rewarding and tactically interesting game if you put in the time... But it does take a lot of time!
