I want a cool setting, with interesting NPCs, cool critters to defeat and a sense of wonder as only living the ocean can do. Seriously, the biggest drawback to underwater campaigns has been a lack of source material. Most water-based campaigns deal with shipboard rules and ship-to-ship combat but not much has dealt with underwater survival. Ever since The Deep by Mystic Eye Games has been out of print, there's been no good campaign setting for underwater adventures. I hope that Sunken Empires fills that niche. I've just picked up a pdf from Paizo so we'll see.
