i never, ever, ever buy guides, but this one is pretty nice and i really liked all the art, so i couldn't help it(plus, it was $13 on amazon :) )
as for the conspiracy theory, i wouldn't doubt it. :)
for guide, yes, it lists complete stats, 1.5/1/.5 responses to all elements, doom weakness, gil, exp, hp, etc, etc. also, drops, steal, and vulnerable status ailments.
