I've been it the hobby for about 5 years. The first 4 of those I went through 22 games. I know around here that probably doesn't sound like much but take a step back: I was adding / changing a game every two months. That is crazy in retrospect. I kinda burned out. I still love pinball but recently I play less games in a month than I used to play in a day. I got IMDN new 11 months ago and that is the longest I've gone yet in terms of adding / changing games. Now, I'm considering adding something new. Currently have MET, IMDN, and LOTR (and Star Trip but that one only halfway counts).
A friend is selling a Hobbit for a good price. I've played probably 30 games on it and I feel like I've only scratched the surface. The layout doesn't excite me but I really enjoy exploring deep rule sets, the theme is a slam dunk for me and my family, and I appreciate JJP production values. I don't think Hobbit is a long term keeper for me but I would really enjoy having it in the house for a few months, maybe even a year or two.
As for ACNC, I've played probably 10 games total on it and I was really impressed. While I'm not really a Alice Cooper fan parse, it fits well with the MET and IMDN and the general Nightmare Castle theme is cool. The layout is unique, the rules seem interesting, and the game really triggered my "just one more game!" urge in the few times I've played it.
