I'll take a shot at answering your question. I thought MCF: Key to Ravenhearst was okay good. It wasn't mind-blowing or anything like that and definitely not creepy.
The second MCF (I think it's called Ravenhearst Unlocked or something) is not out yet. I would assume it'll be out around Thanksgiving, possibly-maybe?
And here is how I rate the MCF games----
1. MCF: Return to Ravenhearst - the best damn game ever made, period! This was truly a mind-blowing game for me. I realize it is an older game and some people probably wouldn't enjoy it as well as today's games. No bells, no whistles, no collectibles. Just awesome gameplay.
2. MCF: Dire Grove - in storyline, it resembled a teenage slasher flick without the gore.
3. MCF: Escape from Ravenhearst - really, one of the most bizarre games I've ever played and I loved it! I honestly think it's one of those "love it" or "hate it" games.
With the exception of MCF: Madame Fate (a HO game with morphing objects, I think it was the first game to introduce the morphing object and it is my most frequently replayed game), all the other MCF games rank below these top 3 and in no particular order.
And remember, folks (before throwing things at me), this is only my opinion.
