Theme and gameplay both have to be good for me to consider buying a pin. Metallica is the best game out there for me. I like the music, and the gameplay is great. Aerosmith is just as good for theme for me, and the art is just as good, but I didn't feel the need to buy it after playing a few times. Dialed in is not a great theme for me, but I also don't care for the gameplay (I actually don't care to play any of Lawlor's games). IMDN was kinda fun, but I only played a couple of games. I probably like enough of their songs that I would enjoy the music. The first couple of games didn't make me want to buy it though. The Hobbit is an OK theme, although the first movie was slow enough that I haven't bothered to watch the others yet. The gameplay intrigued me though, so I am thinking about getting one of those.
Medieval themes are usually a win for me. Music themes are great too.
