I thought Zero Sum Game
was okay, Paths of Disharmony
disappointing and Rough Beasts of Empire
excellent. Seize the Fire
is next of my Titan list, but after all the bad comments I'm in no rush to get to it.
Your enjoyment of Plagues of Night
and Raise the Dawn
depends on your opinion of RBoE. I liked them, but not as much as I did RBoE.
I say try Rough Beasts of Empire
, but if you find you're not enjoying that, quit.
