I played governor to remodel, and my opponent remodeled to a sprawling castle which says, "when you gain this, gain a duchy or 3 estates." to which I was given the option to gain duchy or estates. As nice as it was that I was able to give my opponent 3 estates rather than a duchy, it doesn't seem like it should work this way.
