Got to thinking how (some) people might like a certain type of pin and so their collection might start to look similar.
For example if someone likes a certain type of music like rock, their music collection might not include country, rap, jazz or classical music.
Anyway some people will recommend to another don't get IM if your collection contains a lot of quick type games. However maybe that's what someone like and so might have more of that type of game in their collection.
My two favorite (or 3) are Met pro, IM, and Tron.
Now I do love Tspp and when I had them IJ and TZ were my favorites, I'd like to own again too.
But currently I have all Sterns (8) and all of them being SAM except for Tspp.
I have more newer games 2010 and later (6) against (2) older pins.
I have 4 John Borg designed pins.
