Funny thing, I thought I was diverse in the sense that I believed my collection of pins all play differently. However, when I decided to post my response, I discovered that my collection is not all that diverse at all. Admittedly, there are many common features which I tend to gravitate towards in the selection of my games. I'm not sure if that's a good or bad thing actually...
For example, I like Pat Lawlor games, as well as a mix of Steve Ritchie, George Gomez and John Popadiuk games. Which are reflected in my collection, 11 out of my 16 pins:
PL: TAF, TZ, Funhouse, Family Guy (Stern)
SR: AC/DC Premium, Star Trek Pro, (WPT-previously owned)
GG: RFM, MB, LOTR, (NBA FB-previously owned)
JP: CV, TOTAN (WCS94-previously owned)
