I can't believe there isn't more hullaballoo about this great game. Yes, it is officially "casual" because of some hidden object scenes, and the trivial story, but in my humble opinion, it ranks right along with the so-called "great adventures"
The Elephant Game team has put an enormous amount of work into producing Fate's Carnival, and the result is a wonderfully long, engaging mix of inventory-based puzzle solving, hidden object games (not excessive) and "major puzzles" which are original masterpieces of interactive sequences that rival the best puzzles out there.
Oh, and don't forget the collectibles. There are morphing bobblehead dolls, some of which are characters from past MCF games; morphing tarot cards, lots of cash you can use to buy things for your faithful feline friend. (I'm a miser, so I didn't spend a lot of it, but there's still time, since I am not quite finished. Over a week, by the way)
There is a bonus game of course, which is a fully-developed game in itself, and then there is the Secret Room, available only after everything else is finished. It includes replays of some of the HOS and Major Puzzles, but this time there is no getting into the Strategy Guide; you're on your own.
