Quoted from Nexyss:

When CGC releases an LED upgrade for MMr, I may end up trying to trade my AFMr for one. I really like the game, but I just don't play it much. Metallica is still the go to game. I recently told my wife that I wanted to trade my GnR for a Hobbit, and she said she would rather trade the AFM. To her, the playfield looks older than GnR.
I think the theme of MMr would keep me playing longer. I also think I really like the pop up troll targets. I am pretty sure that is mainly what has me interested in Hobbit. I usually end up buying the games that I enjoy most at a pinball show. First it was AC/DC and GnR, then Metallica, then AFMR, and now the Hobbit was the most fun I had this year. Strangely, I don't remember ever playing MM or MMr at a show.
The Hobbit is not a popular game, but I really had more fun on that than all of the new games that were at GSPF this year (I did not play Houdini though, so I may enjoy that more, I don't know. I didn't play Kill Bill either, but since I couldn't sit through 20 minutes of the movie, probably not one I will love)
