Cons
Con It's fantasy not science fiction
Yes, it has Science Fiction elements, but magic is not science fiction
Con Fantasy not science fiction
Magic and fantasy in space is not science fiction
Con Only 7 classes and only 4 of these are OK
Soldier is excellent, Specialist is very good, and Mystic & Technomancer are ok, but Envoy, Mechanic need much more, and Solarian is pretty horrible.
Con Characters are forced to optimize to be viable
It's unfortunate, but characters are forced to optimize to be viable in combat. This was very evident at the conclusion of the Dead Suns Adventure Path, part 4, which has an adversary so difficult to hit, it was ridiculous. Combats take excessively long and a Vesk unarmed soldier with max Strength is very broken.
Con Solarion is cool in concept, but too multi-ability dependent (MAD)
Charisma as a primary stat makes no sense.
