Ran two quick FA games last night, just to test out the new rules as I have only played twice and my opponent had never played. A few quick reads of the rulebook did not reveal that it really is kinda hard to use in the middle of a game. Many rules are hodgepodged in different sections (via the index) and you have to look in all locations to find what you're looking for.
Firing arcs seemed to be a BIG issue. For example, looking at ship stats, Dindrenzi gun racks don't have arcs listed. Couldn't find anything on them, so we made up our own arcs. Looking for something else, I ran across "gun racks have either port OR starboard", but this was three turns into the game and the damage had already been done. Turrets are not listed in the index, but do not have arcs defined in the Directorate ship stats. I'm sure I'll run across their arcs when I'm looking for something else. Should not be hard to have arcs listed for all weapons and not just some of them. Also resorted to the Spartan forums on several occasions to locate info.
I'm sure it will get better with time, use and familiarization, but I see some definite opportunities for improvement.
What are your impressions of the rulebook?
