Quoted from VectorGamer:
I only have two pins in my collection for now but they get a fair amount of play.
Sometimes I think "less is more." I keep my collection small. Starting 8 years ago it's gone from 1 to 4 pins, then 3 which felt better, now back to 4, and maybe that's too many again. I'm thinking of going back to 3 or even 2 pins.
It doesn't make sense, but I play them more when I have less.
Plus with not so many I can keep them in the living space in the house, rather than a dedicated games room in the basement or wherever.
