I'm a collector, I collect books, used to collect DVDs when before Netflix there was a need for that. Comic books, comic book Omnibus editions etc..
With pinball I just started out buy two old games because I liked playing pinball when I was younger. But later I began to upgrade and try out the better rated pins. Still was more or less a pastime not a big obsession.
But lately (say in the last 4-5) years I've converted to more games that I love and even though don't play a ton, I have my favorites that are nearly permanent keepers. I also got into the rules (begin to understand most of the rules) while I may not be great player to get all the way to the end, the pins I have are in my opinion very well coded and I am trying to get deeper if possible to nibble around the edges of the end game, and maybe someday will defeat a game or get to the Wizard modes.
Some of my pins look easier to crack than others but as yet I'm still plugging away at all in hopes of getting to the Wizard modes without cheating setup.
Kept Potc because it's sentimental first new pin I bought and it still looks new.
