Currently I own 7 of them. Though that will drop to 6 soon (TZ needs to go). I’ve also had a couple others in the past, but those don’t count.
The interesting part for me is that I now own (as of last night) every game on that list that I actually want to own. It reminded me of years ago writing down the top 100 from ipdb and setting out to just play them all. What a crazy hobby.
