I've got it, I've read it, I've played a game with it. Here is my summation: This is not worth $25. It is jam-packed with filler. Look at the sections:
Total length: 96 pages
Ads,credits, quote pages: 3
Full page section intros: 6
Intro: 1 page (1/2 graphics)
New Rules: 3 (2x1/2 graphics)
Earth Alliance Lists: 36 (2x 1/2 graphics)
Pictures of new ships 10 (2 pics per page)
New ships: 16 (15x 1/2 OR LESS text/stats)
The ancients: 9 pages (5 <1/2 text)
Scenarios: 5 (1/2 graphics)
FAQ: 7 (1x1/4 page)
*Subtract out the 1/2 page pictures and you are down to 81 pages
*less the ads, credits and section bumpers and you are down to 72 pages
*subtract out the double pic action shots of the new ships that add 0 content and you get 62 pages
*less the double and triple listed EA ships (24 ships repeated w/o changes): 50 pages.
*less the EA ships not modified from their original SFOS configuration: 31 pages
So thats 31 pages of new content. Even then, it is mostly a few stat line changes, or the FAQ. I really felt like there was very little meat to this book. The only think that seperates it from the Drakh and Dilgar books is the hard cover and the $15 addition to the price.
As for the content:
New rules: Mostly positive, I have no problem incorporating these into the game.
New Ships: I honestly do not see myself using most of the ships in this game. The ancients are not very fun to play against, and the Arm. PL ships are mostly not worth it based on the statlines. I like the new Vorlons and Shadows, however, they are more like their counterpart from the show. The new ISA ships are interesting, and I will find a place for the WS Carrier in my fleet.
EA: Interesting, they took the fleet with the most diversity and then eliminated that diversity my forcing it into three lists. Warlock did not need to be juiced higher. Crusade ear problems and Sag have been argued ad nauseum. Nothing new to add here.
FAQ: I hate paying for FAQs, because they are essentially erata.
So all that said, this should have been a $9.95 softback supplemental. It is definately not on par with SFOS.
