I knew that it was much weaker than other Paradox expansions, like Deus Vult or Divine Wind, but still I thought that it could be worth my money. Even if it offered only few things which I wanted to see I thought that I would show my support to Paradox, for making this great game, by buying the expansion. However it turned out that they pulled the old bait-and-switch fraud (Advertisement video did show that you could edit existing characters, while in expansion you can only create completely new characters [which I don't want to do]) and I was too stupid to fall into that. I believe that my hubris caused this misfortune and now when I have learned that you shouldn't trust even to your favourite companies, I have decided that wait and see strategy is the best, because they might try to pull similar bait-and-switch fraud with second expansion Sword of Islam.
Most disapointing thing however is that people have made complains about this expansion, but Paradox hasn't bothered to reply to them or address these problems in patch. It doesn't look good if expansions has no support.
