I had a smallish collection as kid and into my teens, which is when I developed my nostalgia for the publication. However those are long lost to the recycle bin.
My current collection was put together piece by piece while watching ebay like a hawk, and keeping a spreadsheet of what issues I already had, what condition they were in, and if I was satisfied with said condition.
I did the same for the demo CDs, and the actual floppy disks they included in 1994. That collection still isn’t complete, the floppies in particular are hard to find.
