I'm roughly 13 months in and I've have had 10 Pins (counting incoming)so far. What interesting is that the games I thought were keepers changed as I got deeper into pinball over what is a relatively short time frame still. It's always interesting to flip through people's collection histories here on Pinside. Some people have rarely ever sold a pin, and some are constantly flipping through and I think I'm starting to figure out what works for me finally.

As much as I thought i was going to keep every game I ever bought(even bought extra ramps and decals for the first 4 or 5 games)I've learned in these very short 13 months that I grow tired of machine fairly quick and need to cycle through games with a couple exceptions(Metallica MOPLE and MMr). I love this hobby and hope I feel the same way about it in 5 years as today
