Yep. I still have almost 100% of the games I’ve ever bought since the mid-1980s. The only ones I don’t have are the half dozen or so I took into a consignment shop because I was trying to help them generate business and Cyan’s The Manhole, which I gave to a friend because I thought his kids would like it.
I should have kept all of them. The consignment store went out of business because it was poorly-run and giving away The Manhole was like giving away the premiere issue of a comic book that turns out to be very popular later on. Another thing I missed out on was purchasing some of Infocom’s games in the IBM version because I told myself at the time I would never own an IBM-compatible computer. The packaging is now worth more than the games.
