I did not enjoy this game as much as I've enjoyed other Hidden Objects games. Partially this was a matter of game mechanics. (For example, hiding objects inside of objects, or having to repair or transform them for them to 'count' for your search. Half the time this was figuring out the hotspots within the puzzle screen, and less about actually seeing a hidden pattern inside of a larger picture.)
[Update: I recommend other users play this on 'Casual' difficulty setting, as this will minimize the interface level issues.]
However, I really did get into the whole idea of the House of 1000 Doors itself. That part tying the whole game together across space/time/afterlife was very interesting.
There were aspects of the quest/story that just went ... nowhere. (i.e. What are the Beyond Objects for, and why can't I see my progres, or lack thereof, anywhere within the game interface?) The original game ramps you up to make an interesting choice, and then suddenly ENDS ... without actually giving you an oppurtunity to choose your final outcome at all!
However, I did really enjoy the Collectors Edition content. (Extra Chapter/Myster to solve, Strategy Guide included with game, and Wallpapers, etc.)
I recommend the original game at 3/5 Stars, but I'll give it an extra star with the Strategy Guide, etc. contect included. It was enjoyable, and I did play it all the way through, but it was not compelling! I was slightly disappointed, even for a casual/hidden objects genre game.
Final Rating: 4/5 Stars (With Collectors Edition content bonus)
Value for price? I think this is worth the $10, but this is definitely a game I'd recommend if you can catch it during a Steam Sale.
Update: I did NOT consider the value of the Steam Collectible Card drops when I originally reviewed this. If you merely trade them away for cash in your Steam Wallet, these are worth $1-$3, each [at the time I sold mine]. Expect up to 3 to drop while you play this game. (Theoretically, this game pays for itself, that way.)
