Me and my wife play Lords of Waterdeep more than any other game.  The expansions have only made it better.  We've enjoyed both expansions and then have played with both combined.  Playing with both at once with two people is crazy...it's hard to determine a solid strategy...but it's a lot of fun.  We are so looking forward to playing the expansions with larger groups of people.  I've played a lot of euro-type board games and this is my favorite.
